Convert WebM to MOV

This free WebM to MOV converter changes your WebM (.webm) file into a QuickTime Movie (.mov) file, right in your browser. There is nothing to install, no account to create, and no limit on how many files you convert.

100% private. Your file is processed locally in your browser with WebAssembly — it is never uploaded to a server, stored, or seen by anyone.

The conversion runs on your own device using ffmpeg compiled to WebAssembly (ffmpeg.wasm), so your file is never uploaded to a server. MOV is best for editing, especially on Apple devices, which is the usual reason to convert from WebM.

Why convert WebM to MOV?

  • Note: MOV has narrower support than WebM - convert only when a specific app or workflow needs it.
  • The video is re-encoded to efficient H.264, so the MOV file is usually about the same size as your WebM.
  • Pick MOV when you need a file made for editing, especially on Apple devices.

Frequently asked questions

Is this WebM to MOV converter free?
Yes. It is completely free with no signup, no watermark, and no limit on how many files you convert. It is supported by ads, which keeps the conversion itself free.
Are my files uploaded to a server?
No. The conversion runs locally in your browser using ffmpeg compiled to WebAssembly (ffmpeg.wasm), so your file is processed in memory on your own device and is never uploaded, stored, or seen by anyone.
Will I lose quality converting WebM to MOV?
The video is re-encoded to MOV with a high-quality setting, so the result looks very close to the original WebM. Re-encoding is never bit-for-bit identical, but the loss is minimal.
Will the file get smaller or larger?
Usually similar. The video is re-encoded to H.264 at a high-quality setting, so the MOV file is typically about the same size as your WebM; the container itself adds little.
What is the difference between WebM and MOV?
WebM is WebM (a WebM container, typically VP9 / VP8 + Opus); MOV is QuickTime Movie (a QuickTime container, typically H.264 / ProRes). MOV is best for editing, especially on Apple devices, while WebM is best for fast-loading web and HTML5 video.
How long does the conversion take?
Most files finish in a few seconds to under a minute, depending on length and your device. The first conversion is a little slower while the engine downloads and caches, then later runs start instantly.
