FAQ
Is this signature tool officially provided by CTET?
No. FreeApplyTools is an independent utility. The engine follows official CTET 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 30KB. Our tool fixes the file size.
Common CTET (Paper 1 & 2) Signature Upload Errors
"File size exceeds 30KB"
The CTET portal blocks uploads above 30KB. Our compressor automatically reduces to 3–30KB.
"Signature not in black ink"
Many applicants sign in blue or pencil. CTET 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.
