Converting MOV to WebM: what to know
MOV is converted to WebM to put a video on a website: WebM is an open format that browsers play in the video tag without extra codecs or licenses.
The video is always re-encoded, because WebM allows only the VP8, VP9 and AV1 codecs, and the sound becomes Opus or Vorbis. Encoding runs right in your browser, so long videos take longer. In the settings you can choose the codec, resolution and bitrate, and trim the video.

What happens when converting MOV to WebM
If the codecs inside MOV are supported by WebM, the tracks are copied without re-encoding - quickly and without quality loss. Otherwise the video is re-encoded with the codec, bitrate, resolution and frame rate you choose.
You can also trim the video, rotate or flip it and remove the sound.
MOV files up to 2 GB are supported; the actual limit also depends on the free memory of your device.
