Frequently Asked Questions
Why convert MOV to WebM?
MOV (QuickTime Movie) uses lossless or lossy encoding and is best for Apple ecosystem — Final Cut Pro, iMovie, and macOS video editing workflows. WebM (WebM Video) uses lossy compressed encoding and excels at web-optimized video — streaming, embedded players, and HTML5 video tags with fast loading. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Will I lose the alpha channel?
WebM with VP9 preserves transparency where the source has it — lower-thirds and overlays survive. Odd dimensions get padded to even numbers automatically.
How long does conversion take?
Roughly real-time to 2x on a laptop: a 10-minute MOV converts in 10–20 minutes. Keep the tab open; closing it cancels the FFmpeg worker.
Are my videos uploaded?
No — conversion runs locally in your browser with FFmpeg. Only the final save touches the network — downloads are unlimited.
