Frequently Asked Questions about Scanned Signatures

Helpful answers regarding scanned signatures and dimensions.

What is the standard signature size in pixels for exam forms?

The vast majority of recruitment bodies (like SSC, IBPS, SBI, and RRB) require a signature resolution of 140 x 60 pixels, or an aspect ratio roughly 2:1 to 7:3. UPSC requires a minimum of 350 x 350 pixels.

How do I crop my signature to 140x60 pixels?

Upload your image to our tool. We have already pre-filled Width: 140 and Height: 60. Simply adjust the crop frame over your handwriting and download the cropped file.

Can I resize a signature in centimeters (cm)?

Yes, you can choose centimeters from the unit dropdown. For example, enter 4 cm for width and 2 cm for height (standard SSC requirement).

Why should I avoid using capital letters when signing?

Portals check for genuine signatures. Standard rules mandate signatures in running hand. Writing names in block capital letters is treated as invalid and can lead to form disqualification.

How do I remove the grey background shadow from a phone photo?

Use our built-in contrast slider. Drag the slider slightly to the right to lighten the paper background to pure white while darkening pen ink strokes.
