How to Convert WebM to MOV Online

Upload your WebM file

Drag and drop your .webm file onto the page or click to browse. You can select several WebM files at once to batch-convert them.

MOV is preselected

The output format is already set to MOV, so you can convert immediately. If you need to, adjust the codec, resolution, frame rate or bitrate in the settings panel first.

Convert and download

Click Convert. The MOV file is processed on your own device; nothing is uploaded to a server. When it finishes, click Download to save it (or Download all to get a batch as a ZIP).

Why Convert WebM to MOV?

macOS cannot open WebM in QuickTime, and neither iMovie nor Final Cut Pro will import it. Converting WebM to MOV re-encodes the VP8/VP9 video to H.264 and the Opus audio to AAC, which every Apple app handles natively.

Google Meet, Loom and Chrome screen recorders all produce WebM, so this conversion is the quickest way to bring a meeting recording into a Mac editing workflow, entirely inside your browser.

Private by design: your WebM file is converted on your own device and never uploaded.
MOV preselected: the output format is already chosen, so it is a one-click conversion.
Batch friendly: convert several WebM files in one go and download them as a ZIP.
No limits, no watermark: free for files of any size, with nothing stamped on the output.

WebM vs MOV

WebM (WebM): WebM is the open, royalty-free container built for the web. It pairs VP8, VP9 or AV1 video with Opus or Vorbis audio and streams natively in Chrome, Firefox, Edge and HTML5 players. It is best for HTML5 video, websites and open-source projects.

MOV (QuickTime File Format): MOV is Apple's QuickTime container. iPhones, iPads and Final Cut Pro record and export MOV natively, and it can hold high-quality H.264, HEVC or ProRes streams. It is best for Apple devices, iMovie and Final Cut Pro workflows.

In short: keep WebM when the priority is HTML5 video, websites and open-source projects, and switch to MOV when the file is headed for Apple devices, iMovie and Final Cut Pro workflows. Need a different target? The full Video Converter supports every format listed below.

WebM to MOV FAQ

Why does QuickTime say the WebM file is not compatible?

QuickTime has no VP8, VP9 or Opus decoders. Converting to MOV with H.264 and AAC fixes it.

Will the MOV be larger than the WebM?

Usually a little larger, because H.264 is less efficient than VP9. Lower the bitrate slider if you need a smaller file.

Is this WebM to MOV converter free?

Yes. Converting WebM to MOV on MediaConverter.io is completely free, with no watermark, no sign-up and no daily conversion limit.

Are my WebM files uploaded to a server?

No. The converter runs inside your browser using WebAssembly and WebCodecs, so your .webm file is read and converted on your own device. Nothing is uploaded, which keeps private recordings private and means there is no waiting in an upload queue.

Is there a file size limit for WebM to MOV?

No fixed limit. Because processing happens locally, the practical limit is your computer's memory and patience; multi-gigabyte WebM files convert fine on a desktop browser. Very large files take longer on phones.

Will converting WebM to MOV reduce quality?

The video is re-encoded into MOV. Keep the source codec, resolution and bitrate (the defaults) and the result is visually the same as your WebM; lowering the bitrate or resolution is what reduces quality, and you control that trade-off in the settings panel.

Which browsers support the WebM to MOV converter?

Current versions of Chrome, Edge, Firefox and Safari on desktop all work. Chrome and Edge are fastest because they expose hardware-accelerated WebCodecs decoders.
