Good to know

The converter is ffmpeg running in your browser. It downloads once (about 32 MB), then stays cached.
When the sound or video already suits the new format, it is copied across: instant, and nothing is lost.
Re-encoding video (WebM, AVI, ProRes) processes every frame on your device, so long clips take a while.
Files up to 500 MB. Above that, browsers tend to run out of memory.
Nothing is uploaded. The file is read and written on your device.
