Why convert videos to MP4?
MP4 is the one video format that works everywhere: phones, TVs, browsers, editing apps and every social network. This MP4 converter takes WEBM, MKV, AVI, MOV and M4V files, which are common from screen recorders, older cameras and downloads of your own content, and turns them into MP4 with H.264 video and AAC audio.
- Your screen recording (WEBM or MKV) needs to be shared or edited in an app that only accepts MP4.
- An old AVI video will not play on your phone or TV.
- A platform you upload to asks for MP4 files.
Tips for the best result
- The output is H.264 video with AAC audio at high quality, the most compatible combination.
- Already have an MP4 that is too big? Use the video compressor instead.
- Converting long videos can take a few minutes; you can watch the progress and time left.
