Convert MOV to WebM Online
Turn your high-quality MOV animations into web-ready videos. Support for transparency makes WebM perfect for web design overlays.
Why Convert MOV to WebM?
Web designers and motion graphics artists frequently need video transparency (alpha channel) for overlays and animations. MOV files rendered in ProRes 4444 from After Effects or Motion support alpha channels but are extremely large, often hundreds of megabytes for just a few seconds of footage.
WebM with VP9 codec supports full transparency at a tiny fraction of the file size, making it essential for adding animated elements, lower thirds, logo reveals, or special effects to your website without using heavy GIFs or writing complex CSS animation code.

Frequently Asked Questions

Yes! Unlike MP4 with H.264 which does not support transparency at all, our WebM converter preserves the full alpha channel from your ProRes source.
How small is the file?
Expect file sizes 10x to 20x smaller than the original ProRes 4444 MOV file, thanks to VP9's highly efficient compression algorithm.
Can I use it in OBS?
Yes, WebM is the standard format for transparent stream alerts, overlays, and animated stinger transitions in OBS Studio and Streamlabs.
Is it free?
Yes, our MOV to WebM converter is completely free to use online with no registration required, no watermarks, and no daily limits.
