Guide • Updated: 2026-11-11 • Free, in your browser — your photos are never uploaded
Bank job forms — IBPS Clerk and PO, SBI Clerk and PO, and other public-sector bank recruitments — all ask for a scanned signature, and the size is strict: 140×60 px, under 20 KB. Get it wrong and the application form will not accept your upload.
This guide shows you how to make a clean, accepted bank signature in a few minutes, using only a pen, white paper and your phone.
Bank signatures are small and wide — that is why the size is 140×60 px, much wider than it is tall. Sign on plain white paper with a dark black or dark blue pen, and keep the signature compact, about the width of two fingers. Do not sign big and then shrink it a lot; a signature drawn at roughly the right size stays sharp.
Place the paper flat in bright, even daylight and photograph it from directly above, or use a scanner if you have one. The ink should look black against clean white paper. Shadows, yellow light or a tilted camera all make the signature harder to read — and harder to compress under 20 KB.
Crop away all the empty paper so the signature fills the frame. Then open ResizeHub’s Signature Resizer, upload the cropped image and set the size to 140×60 px. If your notification asks for 300×80 px instead, use that size — both are standard bank-form sizes, so follow your own form.
Set the file-size target to 20 KB and download the result as a JPG. Before you upload it to the bank form, open the file and zoom in: the signature should be dark and readable, with a clean white background. A good bank signature usually lands between 10 KB and 20 KB.
One careful signature, cropped tight and resized to 140×60 px under 20 KB, is all a bank form needs. It takes five minutes, it costs nothing, and your signature never leaves your device — everything is processed in your browser.
