How to prepare your signature for upload
Sign your name on a plain white A4 paper using a black or dark blue pen. Keep the signature within a 10cm × 3cm area. Avoid touching the paper edges.
Photograph or scan the signature. Crop it tightly — remove any extra white space around the signature but keep a small margin. Ensure the paper is flat and evenly lit with no shadows.

Frequently Asked Questions
Should I use black or blue ink for government exam signatures?
Most portals accept either black or blue ink. Black ink typically scans more cleanly for digital uploads. UPSC and SSC specifically state "black or blue ink on white paper." Avoid red, green, or gel pens that may show inconsistently when photographed.
My signature looks blurry after compression — what should I do?
At 140×60px, fine signature strokes can appear thin. To improve quality: (1) scan at 300 DPI instead of photographing, (2) ensure good contrast — black ink on pure white, (3) increase JPEG quality to 80% in the tool. The compressed file will be slightly larger but cleaner.
