MOV vs WebM, in short
MOV is Apple's video format: iPhones, Macs, QuickTime and Final Cut save to it. Outside Apple's apps, some Windows programs and upload forms don't take it.
WebM is the web's open video format, usually with VP8 or VP9 video. Browsers, screen recorders and some download sites save it, but many editors and phones won't open it.
The video is re-encoded to VP8 video with Opus sound, which every browser plays. That runs on your own device, in the browser, so it takes a while for longer videos.
Frequently
Asked Questions
Does converting MOV to WebM lose quality?
It's re-encoded once, at good quality settings. Most people won't see a difference.
Is the sound kept?
Yes. The audio track comes along with the video.
How long does it take?
It depends on the length: re-encoding in the browser uses one processor core, so expect a minute or more per minute of video.
Is my file uploaded?
No. It's processed in your browser, on your own device, and never leaves it.
