Signature Resize in KB for SSC, RRB, UPSC & PAN
Resize a photographed signature (or thumb impression) to the exact pixel size and KB range that SSC, RRB, UPSC, GATE and PAN forms ask for — with auto crop-to-ink so you don't manually trim white space in an image editor first.
What it does
- Auto-detects the ink against the paper and crops tightly around it.
- Presets for SSC, UPSC, bank exams and a fully custom size/KB option.
- Works on a signature signed on plain paper and photographed with a phone.
Private by design
Processing runs entirely inside your browser tab — your photo or document is never uploaded to a server.
Good to know
You can redo the same photo or file as many times as you like with different settings — each attempt starts from your original, so nothing gets permanently altered on your device either.
How it works
Frequently asked questions
Does the paper need to be perfectly white?
A plain sheet with no ruled lines works best — the auto-crop looks for contrast between ink and background, so heavy shadows or coloured paper can confuse it.
Can I resize a thumb impression the same way?
Yes — use the Thumb Impression preset, which centres the mark in a square frame instead of cropping to ink shape.
What if my exam's KB range isn't listed?
Choose Custom size and type the exact pixel dimensions and KB range from your notification.
