Local online video converter

Videoconvi runs FFmpeg.wasm in the browser: change container, quality, FPS and extract audio without sending the source video to our server.

File stays with the user

The source is read only by the selected browser tab. We do not accept uploads, store results or log file names.

Popular formats

MP4, MOV, WEBM, MKV, AVI, M4V, 3GP, MPEG, TS, FLV, WMV, GIF, MP3 and WAV cover common social, archive and messenger workflows.

Load control

Safe mode limits CPU and memory pressure, while preflight estimation shows risk, time and approximate output size.

FAQ

Is the video uploaded to the server?

No. After the interface loads, processing runs locally in the browser.

Do I need to install anything?

No. The engine ships with the page and runs through WebAssembly.

Can I convert multiple files?

Yes. Files are processed sequentially to protect memory.
