How to take a signature photo with your phone that uploads first time

What you need

A sheet of plain white A4 paper, not ruled or yellowish, and a black or dark blue ball-point or gel pen with a medium tip. Fine 0.5 mm pens give thin strokes that fade when the file is compressed to 10–20 KB. Check your notice for the ink colour: some railway and bank exams accept black only.

Sign the way you'll sign at the exam

Use your normal running signature, not capital letters, and keep it the same as on your ID. Sign in the middle of the page, a little larger than usual, so it still reads clearly when shrunk to a small box like 140 × 60 pixels. Sign three or four times and pick the cleanest.

Light and angle

Photograph it in daylight near a window, not under a single ceiling bulb, which throws the shadow of your phone across the paper. Hold the phone flat above the paper, parallel to it, so the signature isn't slanted. Turn the flash off: it leaves a bright spot in the middle.

Crop, clean and compress

Crop close around the signature with a small margin. Then make the paper white: phone photos of white paper come out grey, and grey backgrounds cost KB and look dirty. FitMyKB's Make paper white evens out the light, turns the paper pure white and keeps the ink colour. Finally save it as a JPG inside the KB range your exam asks for.

Common signature rules

Signature limits are usually small: 10–20 KB for IBPS, SBI, SSC, KPSC, WBPSC and JPSC; 10–30 KB for UPPSC and TGPSC; 20–100 KB for UPSC, which asks for three signatures one below the other in a single image (rules checked September 2026). Open your exam's page for its exact numbers.
