Frequently asked questions

How do I convert MOV to WebM?

Click “Choose Files” and select your MOV file (or drag it onto the page). WebM is already selected as the output, so just click Convert and download your WebM file when it’s ready.

Will I lose quality converting MOV to WebM?

When the video inside your MOV file is compatible with WebM, it is copied without re-encoding, so there is no quality loss at all. Otherwise it is re-encoded at high quality. You can pick the quality yourself in Advanced settings.

Is it safe to convert MOV files here?

Yes. Conversion runs inside your own web browser, so your files are never uploaded to our servers or anyone else’s. Nobody can see them, and nothing is stored after you close the tab.

Is the MOV to WebM converter free?

Yes, it’s completely free. There’s no sign-up, no watermark and no limit on how many files you convert. Each file can be up to 1 GB.

Can I convert several MOV files at once?

Yes. Add as many MOV files as you like and convert them in one go, then download them one by one or together as a ZIP file.
