Before you submit
- 20 KB is the usual ceiling for exam signatures and the floor for many exam photos, so check which one your form means.
- A plain white background compresses far better than a patterned one. Crop tight around the face or signature first.
- If your form also names pixel dimensions, use a matching exam page (such as IBPS) so the size and dimensions are set together.

Common Questions
Even the lowest acceptable JPG quality at full size was over 20 KB, so the image was scaled down step by step until it fit.
It aims just under 20 KB. If your form requires at least a certain size, use a page with a minimum; it pads the file up without changing the picture.
It varies, so the tool aims about 3% under the upper limit and, where there is a lower limit, just above it in 1,024-byte KB. The file is accepted either way.
