How do I convert MOV to WebM?

Drop your MOV file onto the converter above, make sure WebM is selected, and click Convert. When it's done, download the WebM file — it usually takes a few seconds.

Is it safe to convert MOV to WebM here?

Yes. MOV to WebM conversion happens entirely inside your browser using WebAssembly, so your file is never uploaded to any server.

Is the MOV to WebM converter free?

Yes — free with no watermark. Signed-out visitors can convert 25 files a day, and a free account raises that to 250.

Will converting MOV to WebM reduce quality?

WebM is a lossy format, but our defaults are tuned to be visually indistinguishable for most files. You can raise the quality under Options.

Can I convert multiple MOV files at once?

Yes. Add up to 5 files at a time without an account, 10 with a free account and up to 500 on paid plans, then download them individually or as a single ZIP.

Can I convert WebM back to MOV?

Yes — use our WebM to MOV converter. Note that converting back and forth between formats can't recover detail lost to lossy compression.
