Audio files


It is the most popular audio file supported by all operating systems and browsers. The format is still taking the music world by a storm. Mp3 was developed by MPEG’s (Moving Pictures Experts Group) and it uses lossy compression meaning some audio quality is lost. It is commonly used to compress audio files for web transmission purposes and storage.


The Free Lossless Audio Codec is an open-source format that holds very high-quality music. It compresses audio files by half their original size without any loss in quality. Currently, almost all popular media players can play FLAC files. It’s the go-to format for downloading high-resolution audio.


It is supported by systems above Android 3.1+

This is the Apple alternative to the popular Mp3 files. It’s a lossy compression format similar to Mp3 but it produces higher quality files taking less storage space. It’s commonly used on iTunes or Apple Music streaming.


It was created by IBM and Microsoft. Almost all CDs are encoded in Wav format as this is the standard. It produces high-resolution audio but it takes a huge space as it’s uncompressed. It can occupy up to 10MBs per minute which is quite huge.


It is supported by systems above Android 5.0+

Ogg Vorbis is a lossy compression format file that can serve as an alternative to Aac and Mp3 thanks to the lack of patent restrictions. It’s very popular with music streaming apps like Spotify.


It is an audio file that uses Aac encoding which uses lossy compression. M4a files are very similar to Mp4 files only that they store audio data. You’ll find them on iTunes if you want to download ringtones. Some m4a files are copy protected so they’ll have .m4p extension.

Video formats


Mp4 was developed by the International Organization for Standardization (ISO) for streaming over the internet and storing multimedia. It uses the lossless (no quality is lost), AAC (Advanced Audio Coding), and AVC (Advanced Video Coding) technologies.

It is the standard video file format as it is supported by most browsers and devices. It can store text, still images, video, and audio. The popularity of Mp4 is credited to its ability to compress video files to small sizes while maintaining high-quality videos.


This is the Matroska Multimedia Container and it can hold limitless videos, audios, pictures, and subtitle tracks, in one file.

It is either a video or audio container developed by the 3rd Generation Partnership Project (3GPP). Their main purpose was to save on space, data usage, and bandwidth hence, the reason they are used to transfer media between 3G mobile phones and the internet.

Image formats


PNG (Portable Network Graphic) file is a format that is popularly used in web design for transparent or semi-transparent backgrounds.

On a single day, there are millions of funny cats’ animations shared online. Even WhatsApp had to include GIFs in their messaging thanks to their popularity. We see them on email images, memes, banner ads, you name it.


Joint Photographic Experts Group (JPEG) is the most popular image file format by digital cameras.  It uses lossy compression hence minute details are removed from your image.

You have the freedom to choose the compression ratio depending on the image quality you desire. Normally, you can have a reasonably high-quality image occupying less storage space.

However, JPEG layers are flattened making it almost impossible to tweak previous edits. So image degradation is a pain in the butt if you keep editing and saving JPEG files repeatedly.

Jpeg images are commonly used to share images on social media or on emails.


It is a raster graphic file that is lossless and stores uncompressed images. It was developed by Microsoft Corporation for the easy exchange of images between devices. These files are much larger in size compared to their compressed counterparts like PNG and JPEG. However, their uncompressed data makes them great for image processing and archival purposes.


It is supported by systems above Android 4.0+

It was specially created by Google to replace Png and Jpg files.  The WebP image format is known to maintain the original image quality while keeping the images smaller. They dramatically reduce the image size by 26%-34% compared to JPG and PNG file formats.

Also, it supports transparency, animation, lossy and lossless compression. This gives users the best of both worlds as they provide both performance and features optimization. They are perfect for web pages as the smaller file sizes make your pages load quicker increasing your search engine optimization.

Using Filestar a typical file conversion with PNG to WebP would be done like this. And converting the other way around is of course the same simple procedure.
