Comment utiliser Convertir une vidéo en ligne — Tous les formats majeurs en 3 étapes

    Pick your source video

    Drop or browse for the video you want to convert. Any format up to 2 GB is accepted.

  2. 2

    Select the target format

    Choose MP4, MOV, AVI, MKV, WebM, FLV, or WMV. Quality presets balance file size vs. visual fidelity.

    Conversion runs locally with FFmpeg.wasm. Your video never leaves your device.

Pourquoi choisir Convertir une vidéo en ligne — Tous les formats majeurs

  • Files stay local

    All conversion happens in your browser via WebAssembly. No upload to a server, no cloud copy.

  • All major formats

    Input and output support MP4, MOV, AVI, MKV, WebM, FLV, WMV, and 3GP. One tool covers every format you need.

  • Quality presets

    Pick from Original, High, Balanced, or Small to trade quality for file size smartly.

  • Parallel encoding

    FFmpeg.wasm uses multi-threaded encoding on supported browsers (Chrome, Edge) for faster results.

  • Unlimited and free

    No sign-up, no watermark, no file-count limit. Convert as often as you need.

Qui utilise Convertir une vidéo en ligne — Tous les formats majeurs

  • Editor compatibility

    Final Cut wants MOV, Premiere prefers MP4, DaVinci eats MKV — convert once to the format your editor loves.

  • Platform requirements

    Twitter caps at MP4; WhatsApp prefers MP4; Discord auto-plays MP4 and WebM. Pick the right container.

  • Legacy device playback

    Older TVs and media players sometimes only read AVI or WMV. Convert to match the target device.

Questions fréquentes

Which formats are supported?
Input: MP4, MOV, AVI, MKV, WebM, FLV, WMV, 3GP, M4V. Output: the same list. Codec remux is used when possible for maximum speed.
Will converting reduce quality?
If input and output share the same codec, we copy streams without re-encoding (zero quality loss). Otherwise a quality preset controls the trade-off.
Is there a size limit?
Single files up to 2 GB work reliably in modern browsers. Larger files may run out of browser memory — consider splitting first.
Does it work on mobile?
Yes on iOS Safari 16+ and Chrome on Android. Conversion takes longer on mobile CPUs — short clips (< 2 min) are best.
Can I convert multiple files at once?
Currently one file per run. We plan to add batch conversion soon.
Is this tool really free?
Yes, unlimited, no watermark, no sign-up. We do not send your files anywhere.
