FAQ
Is this signature tool officially provided by DSSSB?
No. FreeApplyTools is an independent utility. The engine follows official DSSSB notification rules for 2026.
Why is my signature being rejected?
Signatures are often rejected if in wrong ink color (e.g., blue when black is required), on lined paper, or over 40KB. Our tool fixes the file size.
Common Sub Station Apprentice (18-32) Signature Upload Errors
"File size exceeds 40KB"
The DSSSB portal blocks uploads above 40KB. Our compressor automatically reduces to 10–40KB.
"Signature not in blue or black ink"
Many applicants sign in blue or pencil. DSSSB explicitly requires blue or 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.
