20KB is one of the smallest photo limits you'll meet, used on some exam and registration forms. Reaching it usually means resizing the image smaller and lowering quality together. Compressify shows the live size so you can dial it in precisely.

Frequently asked questions
My photo won't reach 20KB — what now?
Resize the longest side to about 400–500px, then drop the quality. 20KB is very small, so some detail loss is expected.
Will a passport photo still be accepted at 20KB?
Usually yes if the portal asks for 20KB — keep the face clear by resizing rather than over-lowering quality.
