Frequently asked questions
What is the UPSC signature size?
UPSC asks for a JPG signature between 20 KB and 100 KB with a width of 350–500 pixels. We output the standard 350x150 px.
Why was my UPSC signature rejected?
Usually the file is under 20 KB or over 100 KB, or the width is outside 350–500 px. The verification report shows exactly which rule failed and the fixed download passes each one.
Does UPSC also need my photo resized?
Yes — UPSC wants a 350x350 px photo between 20–200 KB. Use the UPSC photo resizer for that; both files get pass reports.
