Resize signature: common questions

Which size should I choose?

Every form sets its own limits, and they change between years. Check the photo or signature size printed in your form’s instructions, then type those numbers here. The sizes on this page are common starting points, not any exam’s official rule. For JEE Main, NEET, CUET, CTET and IBPS, the exam pages use each notice’s own numbers.

Is there a limit on how many signatures I can resize?

No. There is no daily or monthly limit and no account, and it stays free for life: use it as often as you like. It all happens on your device, so ScalePDF sets no size limit.

How do I get a clean signature?

Sign on plain white paper with a black or dark blue pen, take the photo in good light from straight above, and crop close to the signature. Keep “Clean up background” on: it turns grey paper white and makes the ink darker.

Is my signature uploaded?

No. The photo is resized right here in your browser or the app and never leaves your device. Nothing is uploaded, stored or shared.
