Hitting 20KB cleanly
20KB is small, so the single biggest lever is dimensions, not just compression. A 1080-pixel photo squeezed to 20KB looks blocky; the same subject at 300 to 500 pixels reaches 20KB looking acceptable.
For signatures and ID photos (the most common 20KB uploads), crop tight and resize down first, then compress. For anything with fine detail, accept that 20KB will be soft, or check whether the form really needs 20KB rather than 50KB.
