How to convert a video
1
Drop the video
MOV, MP4, WebM, AVI, MKV.
2
Pick the format
MP4 works almost everywhere.
3
Convert & download
Transcodes on your device.
Why this works: this tool runs FFmpeg — the same engine pro video software uses — compiled to WebAssembly and executed in your browser. The engine (~30 MB) downloads once on first use and is cached. Because it runs on your device, conversion is slower than a server but your file is never uploaded. On a phone, stick to short clips — transcoding is memory-heavy.
