Frequently asked questions

Is my MOV uploaded to a server to turn it into WebM?

No. The MOV to WebM conversion runs entirely in your browser, with code downloaded from this site and executed on your device. You can check it in the Network tab of the developer tools or by going offline after the page loads.

How long does MOV to WebM take?

It depends on the length, the resolution and your computer. The browser’s hardware acceleration is used when available, and you get an estimate before it starts.

Is there a size limit?

Up to 2 GB and 3 hours of video on desktop; on mobile, 500 MB and 30 minutes (AVI: 1 GB and 1 hour on desktop). If it is over, you are told before it starts and can trim it.

Can I convert several MOV files at once?

Yes. Drop as many MOV files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each WebM or all of them in a ZIP.
