About MP4 files
MP4 is the standard video format of the web. Practically every phone, computer, TV, video editor and social network plays it, usually with H.264 video and AAC sound inside.
These converters turn MOV, MKV, WebM and GIF files into MP4, and turn an MP4 into MOV, WebM, an animated GIF, or just its sound as MP3 or WAV. Videos are processed by your browser, so they never have to be uploaded, however large they are.
