UPSC Signature Resize
Resize a photo of your signature for UPSC exam and interview forms to exactly 140×60px, 20–100KB. The tool auto-detects the dark ink against the paper and crops tight to it, so you don't have to manually trim white space around it in a photo editor.

How to photograph it well
Sign (or take the thumb impression) in dark ink on a plain white sheet — no ruled lines. Photograph it in good light, flat and straight-on, then upload here. Auto-detects the dark ink against the paper and crops tight to it, then compresses to the 20–100KB band automatically.
How it works
Frequently asked questions
What size does UPSC need for a signature?
140×60 pixels, 20–100KB.
Do I need to crop out the white space myself?
No — upload the photo of your signature as-is and the tool auto-detects the dark ink against the paper and crops tight to it for you.
What if my photo comes out slightly under or over the KB range?
The tool re-compresses automatically until the file lands inside the stated range, so you don't need to guess a quality setting yourself.
