What Is CDR (Corel Draw) Format And Why Convert It To PDF?

Almost, all the graphics you can find online are examples of a file of images – they all came from the image file. There are several files that are used in each graphics and all have their own uses just like CDR and PDF format. With the use of the right image file, it means that your design will come up with the perfect quality and appearance.

CDR and PDF file format are both used for vector images – which are curve-based graphics that are outstanding in math equations. Every single dot, shape, and line has a different equation. Vector images are independent when it comes to its resolution. If you zoom in or enlarge a certain vector image, it wouldn’t lose any single detail or pixilation and you get to see it clearly.

What is CDR (Corel Draw) format?

CDR or mainly known as Corel Draw Format is a file extension for the file of vector graphics which is administered by Corel Draw – a program that’s popular for creating popular graphics. The CDR format was first used in Corel Draw application itself which was developed way back in 1987. However, Corel Draw is created and works best for two-dimensional images like posters and logos. At first, it was only made for Microsoft Windows 3, but as of current writing, it also runs on a different version of Microsoft such as Windows Vista, Windows 7, Windows 8, Windows 10, and Windows XP.

What is PDF format?

PDF or Portable Document Format was established by Adobe Systems and is used not just to display graphics correctly but also documents regardless of what kind of device you will use – be it using smartphones, tablets, iPads, web browser, or through an application. When creating a file in PDF format, there’s no character limit and can contain any fonts and images. PDF is also known as the near-universal standard which is often used and requested by printers for the final designs. However, there are things that are not advisable to use the format of PDF such as when making tables, graphs, embedded fonts, and headlines.

Why do you need to convert CDR format to PDF format?

Since CDR format can only be made using the Corel Draw software, there are only a few editing programs as well as users who support the format. Most editing programs support PDF – as it’s the near-universal file format. However, if you are using the Corel software, you can export and convert it to other popular formats like JPG, PNG, AI, BMP, and of course, PDF.

How to export file from Corel Draw?

Corel Draw is a great software and there are users who use it in creating and designing posters as well as logos. However, there are a lot of applications that don’t recognize this CDR format. The main thing you need to do is to export the CDR files into a format that’s readable and recognizable by other application, software, and programs just like the PDF file format. Before exporting files into such format/s, make sure that you check first the list of file formats that supports the application you are using.

Method One

  • STEP 1 – First, you need to open the file on CDR format. After that, you need to activate the certain page which includes objects that you wish to export.
  • STEP 2 – Click the File menu and look for the export button. Once you clicked the export button, an export dialog box will appear.
  • STEP 3 – You can choose for the file format you want or which your device, application or program supports. Create a certain name and path for the file you will export.
  • STEP 4 – If you wish to export the whole page, ensure that “selected only” is not checked. If you wish to export some part of objects or design from a certain page, ensure that you have selected the desired objects and check the “selected only” box.
  • STEP 5 – Now’s the time to click the export button. A dialog box will appear stating some information about the file format you have chosen. Provide the information needed in the dialog box.
  • STEP 6 – Click the OK button.

Method Two

The Corel Draw software has a built-in converter called Macro – which you can use to convert CDR files to any format you want.

  • STEP 1 – Open and run the Macro converter. From the “Macros in,” look and click for the “File Converter” and hit the run button.
  • STEP 2 – Choose which folder contains the file you want to be converted. The files you have chosen needs to be added on the selected files list. Then, click OK.
  • STEP 3 – Pick the folder destination for the files that are being converted and provide the other information needed. Click OK.

What is best for your interactive site? SVG or PNG?

Before moving to this debate let us just clear our concept about what is an interactive site. An interactive or an intelligent site is basically an Internet page that utilizes various types of programming to make a rich, intuitive encounter for the client, for example, it encourages the client to be effectively drawn in with the site. For example, how about we take the instance of a site that shows climate conjectures for a particular district. On the off chance that the site is intelligent, it empowers the client to type in his/her area and demonstrates the point by point climate forecast for that district. The site may likewise show the climate gauges for different nations over the globe and enables the client to zoom and concentrate on explicit districts or control the globe to get a snappy look at the climate in various pieces of the world.

The first truly interactive graphics image system was a project at MIT by Dr Ivan Sutherland in 1963. The technological advancements have enabled humankind to have this sort of fast processing that they were able to enable real-time interactive images. Some technologies that back the interactive graphics include the improvements in algorithms and data structures, the modelling of materials, rendering of the natural phenomena. It also includes the concepts of parallelization. Nowadays, thanks to the internet, rendering is also available as a service on the cloud which has truly empowered the interactive computer graphics.

There are two types of display hardware which include Vector (calligraphic, stroke, random-scan) they are rendered with commands that tell the electron gun where to move and when to turn on/off and lower with more essentials to be drawn, it can start to flash only lines possible, and no filled bitmaps or polygon. Whereas a Raster (TV, bitmap, pixmap) is an image that is represented by a four-sided grid of pixel (picture elements). It is created by electron gun(s), can continually scan in a steady pattern and constant time to redraw any number of elements discretized version of the model and used in displays and laser printers.

Why not A png?

  • PNG format is the kind of Sample-based graphics
    • Based on pixels
    • It can represent and edits pictures-like elements with the use of continuous tones.
    • The use of changed color pixels gives you a smooth blend of the colors.
    • It is not saleable without losing the quality.
    • Detailed images & large dimensions imply large file sizes.
    • Adobe Photoshop is a tool majorly based on raster graphics

Why An SVG?

An SVG image is based on Geometry-based graphics

  • Mathematical calculations form the object lines.
  • Resolution-independent: It can be printed/displayed/scaled at any resolution/size.
  • A large dimensional vector graphic can keep the small file size.
  • It can be easily convertible to raster
  • Adobe Illustrator, Inkscape is an example of geometry based graphics

Adobe’s Flash was a pathbreaking innovation for making rousing and intuitive encounters on the web. While the innovation blurred away, with the consistently expanding interest to construct more noteworthy intelligent and lighter liveliness, SVG has begun to satisfy the need enormously. In this blog, we take you through certain viewpoints on why SVG or Scalable Vector Graphics is staying put and how creator and engineers can exploit this innovation.

With regards to adding pictures to your site, you either pick raster or vector. A raster picture is regularly a photograph comprised of pixels with set goals. In the meantime, a vector picture is made utilizing lines, focuses and shapes. You can utilize it to any size without losing quality, yet such pictures are limited to how much detail they can speak to so they are best utilized for components like symbols, logos and delineations and so forth.

One of the significant advantages of SVG is that it is goals free. Pictures can be scaled a similar way we scale different components in responsive website architecture. The picture looks top notch on any showcase – be it on high pixel thickness show of your most recent cell phone or low pixel thickness show of a standard work area. In this way, on a retina show where a JPG may seem hazy if it’s not sufficiently expansive, SVG will, in any case, look fresh.

SVG inside the program has its very own DOM. It is treated as a different archive by the program and afterwards situated inside the typical DOM of the page. Using inline SVG is invaluable to the site execution since it evacuates the HTTP demand necessities to stack in a picture record. This outcome in your site seeming quicker to the guests improving the client experience.

SVG documents are unique in that they can be altered in designs altering programs, (for example, Illustrator) like different pictures, notwithstanding, likewise in a content manager where the increase can be adjusted legitimately.

Using the PNG converter you can easily convert PNG files to SVG without having to understand the low-level details of the SVG format.

Understanding the Latex Format: What You Ought To Know

Have you ever encountered the term LaTex, but do not know what it means exactly? If your answer is yes, then you have come to the right place. We will try to give you some bits of information about this particular typesetting so that you can use it much more effectively in the future.

The Definition of Terms

The term LaTex actually refers to Lamport Tex. It is basically a different type of documentation and preparation system for word processing. When writing on the computer, we usually use plain text or formatted text like those that you see utilized in various word processing programs such as Microsoft Word.

LaTex, on the other hand, is a kind of document format that is usually utilized for other files aside from word processing. If you are trying to create the PDF or DVI file, you would need to use a TeX file. These files are more suitable for printing and distribution.

What Is A Tex File?

A Tex file is a type of document that uses LaTex as its format. If you are going to publish a book online, this is the perfect typesetting and font format that you should use.


Latex is another format for documentation and was developed by Donald Knuth in 1978. This particular type of typing format is usually used when typing mathematical formulas. It is also known as one of the most sophisticated typographical systems in the digital age.

It is also popularly used in academia especially in subjects like Computer Science, Economics, physics and other subjects related to Mathematics and the Sciences.

It is also the most recommended formatting system if you are going to use Unix installations in any type of project.


A text file is designed to reach a specific goal. To allow users to publish various reading materials and similar documents with minimal effort.

It would also allow digital users to be able to read various files online easily no matter what machine is used. By using this TeX file, people have more access to documentation without having to worry about its readability and usability online.

The good news about this is that the source code for this particular typesetting is available in the public domain. This means that other programs are allowed to modify the system as they see fit in order to produce possible improvements. The only stipulation is that they use a different name for each new iteration of the LaTex typesetting.

The Uses

As mentioned earlier, this particular typesetting is currently being used in various technical fields such as Computer Science, Engineering, and Physics. TeX has become the standard for published books in terms of typesetting and font usage. Various journals in these fields have also produced a lot of the reading material using this specific format.

This means that if you have a textbook in science or math for school, chances are it was published in this particular format.

During its creation, Donald Knuth believed that there is no single typesetting that will be able to fit everyone’s different needs. This is why he designed the typesetting with many program hooks that would specifically allow users to further develop this particular font and publishing format.

This particular typesetting is also utilized when writing formulas and mathematical expressions. It can also be used as parts of various syntax for computer commands both online and off. These types of commands usually start with a backslash with the elements being grouped in braces just as you would in a mathematical expression.

One advantage of using this particular typesetting is that it is easily flexible. If you’re using the Tex format, you can easily change the elements of your document syntax right away. You won’t have to think about complicated commands to type in.

All you need to do is to make sure that you use the right command string to change the syntax of your document and everything else will follow.

Here is an example of the page using TeX and LaTeX macros.

Plain Text Version: Hi, How are you?

To answer this, you would type in \I’m OK%. The % will signify the end of the string. This will not be shown in the results.

The file extension commonly used for Tex files would be .tex. In addition to this, everything that would follow the percentage sign on the document would be considered as a comment. This is why you have to be careful about what you typed after the percent sign.

The Final Words

These are just some of the many advantages that you would get from using this particular typesetting in the future. If you really want to have the best-published book in Math or Science, Using LaTeX would certainly help you with a lot in terms of achieving your goal.

Our file converter supports a number of typesetting formats that you can convert your files to also our LaTex Converter can convert Tex files to PDF online, without needing to download any software.

A Short Overview of AAC Music File Format and how it Compares with MP3

In the world of digital music, the first music file format that will come to most people is the MP3 – but it’s not entirely accurate. There are several music file formats available which can be used in every song stored in all devices, computers, and laptops.

All music comes in different format and sizes. Most of you are familiar with MP3 format, but have you ever heard about AAC format? Both MP3 and AAC are in lossy formats – since they always used for regular music listening. Lossy formats save a lot of space, giving you the opportunity to save more music in your storage. With this format, there are sound waves that are being removed to reduce the file size – which also affects the music’s quality. Additionally, it is not recommended to use lossy formats in professional events or settings because it requires high-quality music.

What is AAC Music File Format?

AAC is also known as Advanced Audio Coding. It is an example of lossy codec which provides a small size of audio files and they are great for streaming online. However, AAC music file format is not helpful for the replica of an original recording. Music or audio files that are in AAC format are ideally used in mobile phones and tablets.

Advanced Audio Coding (AAC) was established in the year 1997, being the successor of MP3. Though it was popular since it was developed, it never overtook the MP3 as the most used and popular file format for many people. AAC used more advanced compression algorithm compared to MP3 format. If you are going to compare two same recordings but in a different file format such as AAC and MP3, the AA music file format will have a better quality of sound than MP3.

Though MP3 format is the most popular format among all music file formats, AAC is the most used today. Furthermore, AAC is the standard method of audio compression used by different applications like Android, iTunes, YouTube, iOS, late versions of Nintendo portables and PlayStations.

What is MP3 Music File Format?

MP3 is the short term for MPEG-2 Audio Layer-3 and was developed by MPEG (Moving Picture Experts Group) which is one of the groups in the industry that produces technical standards. Music that is saved in the format of MP3 has an amount of size compared to other music saved through a CD-quality format. Just like AAC, all music that is in MP3 format save extra storage space through compressing the file’s data. When you say compressing music or audio files, it means some parts that would not impact the quality of music listening experience are removed – the very low and very high ends of audio.

Being the most popular music file format worldwide, MP3 format is not used in iTunes just like AAC. However, the MP3 music file format is compatible with all devices in iOS.

Which One You Should You Use?

Now that you already understand and know the differences with each other, you might be confused about which music file format you should use. Generally speaking, there’s nothing to be confused for because it does not matter which music file format you use as long as you have high-quality speakers to hear the better quality of the music will be produced. AAC and MP3 file formats are compatible with every devices and player, so you don’t have to stress yourself out thinking which one is better for you.

However, if you are going to compare it, AAC music file format has a higher quality of sound and does have smaller size while MP3 is the more compatible compared to the latter and that’s what makes it popular among other file formats of music. You would not exactly tell which music file format comes first because every person has its own needs and preferences. As long as it works for you and your device and meets your needs, it’s the best one.

Final Few Words

The debate between AAC and MP3 is truly a tough scenario. However, not all people have the same requirements when it comes to music. Different people, different needs, and different preferences. All has its own taste when it comes to music and most people only want to hear good music regardless of its file format or file size – as long as it plays on his or her device. Whichever file format you will use is not a big deal. What’s more important is you enjoy the music you want to listen and it provides you benefits for yourself.

Music is every person’s companion through thick and thin as well as the ups and downs of life, thanks to the developers of AAC and MP3, because of them the world was able to listen to great-quality songs.

Our AAC converter supports a variety of formats that you can convert your AAC files to, and vice versa, you can also use our free MP3 converter to convert your music files to other formats. Our file converter also supports conversions between AAC and MP3.

Happy converting!

Learning All about CSV Files or Comma Separated Values

Are you interested to learn about what the term CSV actually means and how it connects to the world of computations and symbols that end up building data strings for websites all over the globe? Please read this article to find out everything you would want to know.

We will provide you with some information about the CSV files and extensions and how you can use it to your advantage when creating unique command strings for programs down the line. However, before going any further let us first define the term CSV.

Definition Of Terms

The term CSV refers to comma-separated values or any delimited text files that use commas to separate and divide a string of significant character symbols into individual sets. A CSV file can store both numbers and text expressed as plain figures.

Each line of the file also consists of more fields that are separated by commas. This particular punctuation mark serves as a field separator that can also serve as a file name for this particular format.

The CSV file format is not the standard format used in normal text. The idea of separating fields with commas is pretty clear. However, it can be confusing when a certain field contains commas as part of the string. This is similar to embedded line breaks with commas as part of the character string.

Thus, CSV files may not be able to handle such a large amount of data. Most of the time, developers also use other punctuation marks in conjunction with the comma to divide it from the string as a unique element. An example of these additional punctuation marks in a string would be the quotation.

However, this does not solve everything. Some strings may require the use of quotation marks as part of the character set as well in order to be implemented. In this case, CSV files can also make use of escape characters and sequences for implementation.

Other Connotations

CSV can also refer to delimited or separated file formats and character strings that use different punctuation marks as a field separator. Here are some examples:

  • The Semicolons
  • Tab and space-separated values

A delimiter that is invisible from the character string much like “tab”, keeps the format simple and easy to understand. Different CSV files are still usually given the .csv extension despite having other punctuation marks as field separators.

Many of the applications that accept CSV files have the embedded option to accept either the delimiter character or the quotation marks. Semicolons are also used as a field separator in some European countries.

The Exchange Of Data

Data files with comma-separated values are commonly used by consumers, business entities as well as various scientific applications. The most common use among these would be as an integral part of a tabular representation of data. The data exchange occurs usually between and among programs that operate within non-compatible formats. Most of these non-compatible formats are undocumented or copyrighted properties.

This usually works because of the support of so many programs for many variations of the CSV format used for data importation.

For instance, users may need to execute a data transfer from one database program to another. One or the other database may use spreadsheets to store data in either proprietary or undocumented format.

When this happens, the program user may export the file using a CSV extension which can then be imported into the spreadsheet of another program to be converted into a compatible file.

Specific Definitions

Standard specifications have been proposed for CSV files by RFC 4180. These are the definitions commonly used. However, within the regular field, the term CSV usually refers to many types of file formats.

This is why the term CSV can refer to files that include the following:

  • Plain text with Unicode character strings.
  • Records (one record per line)

Records are usually divided into different fields that are separated by delimiters which can refer to single characters or commands such as space or tab option. The usual punctuations can also serve as delimiters (Commas, semicolons, quotations, etc.).

In addition, every record usually has the same field sequence.

Within these parameters, there are many known variations used. This is why there’s no usual specification for every file that is claimed to be a CSV. In addition to this, most of the applications supporting these file types recognize the first few lines of the file as a preview and have specifications regarding the delimiter characters and quotes.

If any of these variations fall beyond the scope of the supporting program used, programmers and coders are usually called upon to work on the file manually, using a text editor. These professionals often write scripts to reformat the whole file if and when necessary.

Closing Statement

These are just some of the important facts you need to know about comma-separated values within files. With these significant pieces of data, we hope that you will be able to create your own CSV string sooner rather than later.

You can use our CSV converter to convert your CSV files to many popular output formats or you can use our XLS to CSV Converter for reverse conversion. We also support a lot of other XLS and XLSX conversions.

FLAC format: What Is It? History and Uses

What is FLAC?

FLAC is an acronym for Free Lossless Audio Codec, it is almost like MP3 the only difference is that MP3 make use of what is called “lossy” compression. FLAC is ranked the popular and fastest lossless audio codec when digital audio is compressed by FLAC such audio is reduced to a size that is about 50% to 70% of the main size of the audio file although the reduced file is a matching copy of the initial audio file. The space taken by an audio file compressed by FLAC is quite smaller than the size it is before compression while maintaining the same quality. With the free lossless audio codec, every single sound made in an audio file can be heard, some of these sounds might not necessarily be a sound that can be comprehended or heard by an average human but if you have more sensitive ears you would love the standard quality FLAC lossless compression, this fact is what differentiates FLAC from MP3. Using MP3 the audio file sound is filtered that is some fragment of the sound information has been discarded. Using FLAC there is no loss of information, FLAC is supported by a lot of electronic devices such as car stereo, portable players, home stereo and the likes. FLAC is quite an error-resistant because of the framing it has, this feature helps reduces the effect of damage to the part where the error occurs and FLAC makes CD archiving possible. This free lossless audio codec is made in an open format, therefore, it is quite impossible to generate loss if the audio file compressed is needed to be converted into some other format in the nearest future. There is a verify option in FLAC and this option helps in decoding the encoded file stream in parallel with an encoding process with a comparison of the compressed file to the original file and if any error is detected whatsoever the process will be aborted.

History of FLAC

Sometime in the late nineties, the MP3 was creating worrisome effect based on the rampant illegal sharing by users over Napster. FLAC was developed in the year 2000 and the implementation of FLAC was made on the 15th of January 2001 with a Beta version of 0.5. On the 20th of July 2001, another version was released which was version 1.0. By 29th of January 2003, FLAC project and Xiph.org Foundation made public their incorporation and this was made known under the Xip.org banner. You would ask what is Xip.org? Xip.org is a foundation that is responsible for other free compression formats such as Theora, Vorbis, Opus, and Speex. A new version of FLAC was released on the 26th of May 2013 and from this point onward development was shifted to the Xip.org git repository. FLAC comprises of the stream format and also plugin inputs for countless media players. There is also something called Ogg FLAC, this is a format that uses Ogg container which was incorporated by Xip.org for streaming.

Uses of FLAC

FLAC is supported by several apps on different types of mobile phones and PC such as IOS, Android and Windows (specifically Windows 10). FLAC is good when it comes to downloading files on the internet as it helps reduce the time use in downloading. FLAC can be used in streaming music files on the internet, compressing audio files, typically not all music or media players can play a FLAC file but there are quite a number of quality media players that do this, an example is VOX music player for iPhones and Mac. There have been some comments about no difference between FLAC and MP3 and this is so not true. FLAC music quality is experienced with a good headphone and a good sound system because sometimes without this it might be quite hard to distinguish between these two. The quality of a FLAC audio file is clear and succinct as the original sound recording of that audio file. The quality of audio that FLAC gives is way better than that of MP3.


All being said about FLAC, it is evident that FLAC is not as known by all when compared with MP3, based on the fact that FLAC more than x2 of an mp3 file but smaller when compressed. Although with the compression there is no difference whatsoever in the sound quality of FLAC audio file. If you cannot really differentiate between these two, have you made a comparison using a headphone with great sound quality? Some music player or streaming service uses FLAC as an upload option and also a download option.

Our FLAC Converter page has a lot of conversion types that can be done from that format, the most popular ones are FLAC to MP3 or MP3 to FLAC. Our formats page has a full list of all the supported conversion types.
