Video Converter
A video converter moves a recording into a different container or codec, like MOV to MP4 or MKV to MP4. FileFlip does it in the browser, which means a two-gigabyte file is read from your disk instead of being pushed up your connection and back down again.
Every one of them runs in the browser, on this page, with no upload and no account.

How video conversion works here#
mediabunny handles the formats your browser can encode natively through WebCodecs, using the hardware encoder in your machine and downloading nothing. Anything WebCodecs cannot do falls through to FFmpeg compiled to WebAssembly, a 32.3 MB module that is cached after the first conversion.
Some conversions are a remux rather than a re-encode. MKV to MP4 normally moves the same H.264 stream into a new container untouched, which is why it finishes in seconds and costs no quality. Changing the codec, say H.264 to VP9, is a real re-encode and takes roughly as long as the video is.
Pulling the audio out of a video counts as a video conversion. MP4 to MP3 keeps the sound and discards the picture.
Every engine, its exact version and its download size are listed on how FileFlip works, along with how to check for yourself that nothing is uploaded.
