Official 2026 Size & Format

Upload JPG or PNG, up to 5 MB — we'll convert it to match the spec above.
How this tool works
This tool scales your signature to its own width, up to 500 pixels and saves a JPG between 5 KB and 20 KB for SI (Sub-Inspector). It keeps quality as high as the 20 KB limit allows and pads a file that comes out under 5 KB without changing the image. It does not change ink colour, so sign in black ink on plain white paper.

FAQ
Is this signature tool officially provided by UP Police?
No. FreeApplyTools is an independent utility. The engine follows official UP Police 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 SI (Sub-Inspector) Signature Upload Errors
"File size exceeds 20KB"
The UP Police portal blocks uploads above 20KB. Our compressor automatically reduces to 5–20KB.
"Signature not in black ink"
Many applicants sign in blue or pencil. UP Police 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.
