How this tool works
This tool scales your signature to 230 × 75 pixels and saves a JPG between 10 KB and 20 KB for CTSE (Diploma / ITI Level). It keeps quality as high as the 20 KB limit allows and pads a file that comes out under 10 KB without changing the image. It does not change ink colour, so sign in blue or black ink on plain white paper.

FAQ
Is this signature tool officially provided by TNPSC?
No. FreeApplyTools is an independent utility. The engine follows official TNPSC 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 CTSE (Diploma / ITI Level) Signature Upload Errors
"File size exceeds 20KB"
The TNPSC portal blocks uploads above 20KB. Our compressor automatically reduces to 10–20KB.
"Signature not in blue or black ink"
Many applicants sign in blue or pencil. TNPSC 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.
