About the WebM to MOV
WebM to MOV converts WebM video into MOV, right in your browser. WebM is the open, royalty-free web video format — smaller files that play in every modern browser, ideal for websites. MOV is Apple's QuickTime format — high quality and the default from iPhones and Macs, but less universal than MP4 elsewhere.
Converting WebM to MOV gives you an Apple-friendly QuickTime file that Final Cut and iMovie handle natively. The video is re-encoded to the target codec at high quality; converting cannot add quality the source never had, so start from the best original you have. Everything runs on your device with a WebAssembly build of ffmpeg, so your video is never uploaded — it is private, free and has no watermark. These tools are best for short clips, since the work runs on your device; the engine downloads once (about 25 MB) and is then cached.
Frequently asked questions
Is my video uploaded?
No. The conversion runs entirely in your browser with ffmpeg (WebAssembly). Your video never leaves your device.
Will converting WebM to MOV lose quality?
The video is re-encoded to the target codec at high quality; converting cannot add quality the source never had, so start from the best original you have.
Why is it slow on long videos?
The work happens on your own device rather than a server, so long or high-resolution clips are demanding. Trim first or use a shorter clip for best results.
Is there a watermark or sign-up?
No. It is completely free, needs no account, and never adds a watermark.
