Common Reasons Signatures Are Rejected (And How to Fix Them)
Avoid these 4 common rejection pitfalls during document upload in SSC, UPSC, and Banking application forms:
File Size Outside 10KB–20KB Range
Uploading a file under 10KB or over 20KB triggers a mandatory upload validation error on server submit.
Excessive Background Margin
If you don't crop white space, your actual signature will appear tiny and illegible on the admit card.
Incorrect File Extension (PNG/WebP)
Most portals strictly mandate .jpg or .jpeg. Our resizer automatically converts PNG to JPG format.
Ruled Paper or Blue Line Artifacts
Always sign on pure white unruled paper so automated optical verification can read your signature.
