What changes in this conversion

  • Only the audio track is kept — the video picture is discarded, so the result is far smaller than the original RMVB file.

How to use

  1. Add your RMVB file

    Drag the RMVB file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm FLAC as the output

    FLAC is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.

  3. Run the conversion

    Press the convert button. Video is re-encoded frame by frame on your own machine, so a long clip can take several minutes. The tab has to stay open.

  4. Download the FLAC file

    When it finishes, download the FLAC file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting RMVB to FLAC really free?

Yes. RMVB to FLAC conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my RMVB files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the RMVB file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Does the picture disappear when I convert RMVB to FLAC?

Yes — FLAC is an audio format, so only the soundtrack is extracted. The video track is dropped, which is usually the point when you want just the audio.

Is there a file size limit for RMVB to FLAC conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
