What changes in this conversion

  • MOV does not support transparency, so transparent areas are filled with a solid background (white by default).
  • The picture and sound are re-encoded to H.264 video with AAC audio inside the MOV container, which is what makes the result play on the widest range of devices.

How to use

  1. Add your WEBM file

    Drag the WEBM 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 MOV as the output

    MOV is already selected as the output format on this page. You can pick the resolution. Encoding is the slowest part, so smaller resolutions finish sooner.

  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 MOV file

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

Frequently asked questions

Is converting WEBM to MOV really free?

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

Are my WEBM files uploaded to a server?

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

Will my transparent background survive the WEBM to MOV conversion?

No — MOV has no alpha channel, so transparent pixels are replaced with a solid background. If transparency matters, convert to PNG or WebP instead.

Is there a file size limit for WEBM to MOV 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.
