    FLAC is lossless — your audio keeps every detail, so there is no bitrate to set.
    Keep original unless a device or app asks for a specific rate.
    Mono halves the size of voice recordings with no quality downside.

    Working…

    ✅ Done — your FLAC files

    🎉 Free forever. No sign-up. No credit card. No limits.

    This converter runs entirely in your browser — convert as many files as you like, as often as you like.

    How it works

    1. Add your MP4 files — drag and drop them into the box above, or click to browse. You can add a whole batch at once.
    2. Pick your settings — use a one-click sample-rate preset, or fine-tune the output yourself. FLAC is lossless, so there is no bitrate to sacrifice quality over.
    3. Convert & download — hit the convert button and save your new FLAC files. The video track is discarded and the audio is re-encoded losslessly; everything happens in your browser.

    Note: the conversion engine downloads once on first use (about 9 MB, then it stays cached) — after that, conversions start instantly.
