Most application forms ask for a scanned signature within a small KB range and fixed dimensions.
Upload a clean signature image that matches the size the portal accepts.
Colleges ask for the candidate signature alongside the photo, each with its own limit.
A clean white-background signature JPG is easy to place on letters and forms.
Upload the photo. Whiten background is already on, which turns the paper pure white; plain white compresses to almost nothing, so more of the size budget goes to the signature itself. Enter the pixel or cm size from the form if it gives one, keep or change the KB limit, and compress.
Different limit? Type it in, or use Compress Image to KB. For the photo that goes with the signature, use Compress Image to 20KB or 50KB.
