A single compressed file per input, at a quality level you choose rather than a fixed default. If the result is still not small enough, reducing the pixel dimensions will do more for it than pushing the quality slider further down.

A lossy source yakanga yapfuura mhedzisiro yeimwe quantumization pass, uye chero chiitiko chine kudzokorora-kunyora zvinowedzera imwe. Kwavanogona kuita basa pasina kusvibisa pixel data isu tinoita kuti panzvimbo, uye apo hazvigoneki iwe sarudza quality factor iwe pachako kupfuura kuwana zvakajairika default.
Yeah. Drop yose set mu upload nzvimbo uye ivo queue mumwechete neimwe configuration - kuti ndiyo yakakosha chikonzero kuita izvi mu browser kupfuura imwe faira panguva imwe mu editor. Free accounts run imwe faira pa batch; a pass lifts that.
