Several recruitment exams and government forms — SSC, railway recruitment, and some state PSC applications — require a scanned left-thumb impression alongside your photo and signature, sized to a specific small pixel dimension and KB limit, usually similar to the signature specification.
This tool resizes and compresses a photographed or scanned thumb impression to the exact size a portal expects, keeping the ink pattern legible at the smaller dimensions rather than compressing it into an unreadable smudge.
For a clean scan, press your thumb onto a stamp pad and then onto plain white paper, avoiding smearing, then photograph it in good even light before uploading here — a blurry or smudged source image will still look poor no matter how it's resized.
Presets cover SSC, UPSC, RRB, IBPS, SBI, NTA, IB, State PSC, CAPF and more — 86 exam presets in total across the toolkit.
You can enter a custom pixel size and KB limit directly.
SSC CGL, SSC CHSL, several railway recruitment board (RRB) exams, and some state government recruitment portals require it — check your specific exam's application instructions for the exact pixel and KB requirement.
This tool only resizes and compresses; it doesn't adjust ink contrast. If the impression is too faint, re-do it with slightly more ink pressure and a fresh stamp pad before scanning again.
