Jinsi Inavyofanya Kazi

Converting between video containers and codecs normally means uploading to a conversion site. This converter runs the real FFmpeg engine in your browser, so the file never leaves your device.

1
FFmpeg.wasm loads once
The WebAssembly build of FFmpeg (~30 MB) downloads on first use and is cached for instant reuse.
2
You pick a target format
Your video is loaded into FFmpeg's in-memory filesystem. Nothing is uploaded — it stays in your browser's RAM.
3
FFmpeg re-encodes to the new format
The same x264/VP9/MPEG-4 encoders desktop FFmpeg uses run locally on your CPU to produce MP4, WebM, MOV, MKV, or AVI.
4
The converted file is offered for download
The result is handed back as a downloadable blob and (for web-playable formats) previewed in-page.

A common need is making a WebM play on an iPhone (iOS Safari can't play WebM) — converting to MP4 fixes it instantly, with no upload, no queue, and no watermark.
