What is a MP4 file?
MP4 is the universal video format — plays on every device, browser and platform without extra codecs.
First released in 2001 by ISO/IEC JTC 1, it uses lossy compression and no transparency, which makes it best suited to video sharing, streaming and playback on any device.

MP4: frequently asked questions
Is MP4 the best format for video?
For broad compatibility, yes — it's accepted everywhere. If you need smaller files at the same quality, WebM with VP9 or AV1 is more efficient but less universally supported.
Is the conversion private?
Video conversion is processed on our servers using ffmpeg — your file is deleted immediately after conversion and never stored.
