Why Resize Signature to 20KB?
Most online exam and government portals have strict upload rules, which require your signature under 20KB. If your file is bigger, you’ll face issues like signature not uploading size error or instant rejection during form submission.
That’s why candidates need to resize signature to 20KB or compress signature to 20KB before uploading. A large image from a phone or scanner usually exceeds limits, so using a tool to reduce signature size to 20KB online becomes necessary.
This is especially common in exams like SSC CGL, where even a small size mismatch fails the upload. Keeping your signature less than 20KB ensures smooth submission and avoids repeated errors.
