The export is a bundle of choices.
Media exports combine dimensions, frame or sample rate, codec, bitrate and duration. File size is the result of those choices, not one magic quality switch.

Browser support varies. WebM is used because it can be encoded directly by modern browsers without a server.
Useful to know
Four things worth knowing.
Exporting is not mastering.
A browser utility is good for a focused conversion or edit, but it is not colour grading, audio mastering, motion tracking or a full timeline.
Play the whole thing.
Play the exported file from beginning to end and check picture, sound, crop, timing and orientation.
Match the destination.
Play the export all the way through once. Broken audio, a bad final frame or a mistimed subtitle often hides near the end.
