Common PNB Specialist Officer (Civil, Electrical, Mech) Signature Upload Errors
"File size exceeds 20KB"
The PNB portal blocks uploads above 20KB. Our compressor automatically reduces to 10–20KB.

Many applicants sign in blue or pencil. PNB explicitly requires black ink on plain white paper.
"Signature scanned on lined/ruled paper"
Use blank white paper. Notebook lines in the scan are a common rejection reason across government exam portals.
