Compress an image to 20 KB
Set 20 KB as the target and get a file that fits — at the highest quality that stays under the limit.
Common questions
Which forms ask for 20 KB?
A 20 KB limit is common for signatures on Indian government exam forms. Some portals also apply it to thumb impressions. Photographs usually get a larger allowance.
Will 20 KB still look clear?
For a signature or a small passport photo, yes. For a large detailed photograph, 20 KB is very tight and the result will be soft. The tool always keeps the best quality that fits, so if it looks poor the limit itself is the constraint.
The result came out at 8 KB, not 20 KB. Is that a problem?
It can be. Several exam portals enforce a minimum size as well as a maximum and will reject a file that is too small. If your form has a minimum, use the exam preset on the relevant page rather than a plain KB target — the presets pad the file to satisfy the floor.
How do I get a smaller size without losing so much quality?
Crop the image tighter before compressing. A photo cropped to just the face carries far less detail than a full-frame shot, so the same 20 KB budget stretches much further.
