MP4 Video Format MP4 Converter
MP4, sometimes called MPEG4, is one of the most common video formats. MP4 was developed to be easily played and shared. It was originally developed by the Moving Picture Experts Group (MPEG) but has become an ISO standard, meaning that it’s now maintained by the International Organisation for Standardization. As MP4 is a standardised format, it will normally play easily on most devices and media players, including Windows Media Player, QuickTime, and VLC. MP4 is usually the preferred format for uploading videos to YouTube, Vimeo or other websites.
MP4 videos are made up of video and audio elements that are compressed separately. The video part is usually compressed with MPEG-4, and the audio is usually compressed using AAC, which is the audio format associated with iTunes. Because both file elements are compressed, MP4s normally have a smaller file size than many other video formats, but still maintain relatively high quality for sharing online.
AVI Video Format AVI Converter
AVI is a common type of video file, which Microsoft developed for Windows and launched in 1992. AVI is short for Audio Video Interleave, and like many other video formats, AVI files are container files that include both video and audio in different codecs. AVI files are compressed but to a lesser extent than some other video formats; this means they tend to have higher quality video but may also have a larger file size.
Although MP4 is probably the most common video format and an ISO standard, AVI files are also widely supported and can be played by numerous media players, including Windows Media Player, QuickTime, VLC and MPlayer. If you are having problems playing an AVI file, you may need to convert it to another format like MP4 first, or you may be able to play it by first installing an additional codec for your media player. AVI is one of the formats that can be used to upload videos to YouTube or Vimeo, and social media sites like TikTok, Instagram and Facebook also support AVI videos.

With these online tools, you usually just have to upload your video and click to convert it, before downloading your AVI file.

Whether AVI is better than MP4 depends on what you are using the file for. MP4 files are smaller, so are easier to share, and they also work on most devices and players. However, while MP4 videos will usually play on Windows Media Player, AVI is the format that was designed for Windows. If you’re using Windows video-editing tools, you may prefer to edit AVI files.
You can easily create AVI video files using an online conversion tool like Zamzar – just upload your MP4 file, click to convert it, and then download your video in the new format.
