What changes
Both formats are lossy. Converting decodes the file and compresses it again, so it loses a little more detail on top of what the original had already lost: the result is slightly worse than the file you started with.
The file gets smaller: WebM stores the same content in less space.
Both support transparency, so it’s kept.
When it’s worth it
Choose WebM for: Websites and browser playback. Royalty-free, and plays in every modern browser.
Stay with MOV for: Editing and Apple devices.

Questions
Does converting MOV to WebM lose quality?
A little. Both formats are lossy, so the file is compressed again and loses a bit more detail.
What is the WebM format?
The container Google designed for the web, carrying VP8 or VP9 video with Opus or Vorbis audio. It’s royalty-free, which is why open-source projects and most browsers prefer it.
What is the MOV format?
QuickTime File Format, Apple's video container and the one that still carries the professional intermediate codecs used in film. It stores video, audio, timecode and metadata in separate tracks, and it’s the native working format of editing software on Mac.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
