FAQ
Is this signature tool officially provided by VNIT?
No. FreeApplyTools is an independent utility. The engine follows official VNIT 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 20KB. Our tool fixes the file size.
Common Group C (Sr. Asst / Sr. Technician) Signature Upload Errors
"File size exceeds 20KB"
The VNIT portal blocks uploads above 20KB. Our compressor automatically reduces to 10–20KB.
"Signature not in black ink"
Many applicants sign in blue or pencil. VNIT 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.
