Signature resizer for online forms

Sign on white paper and take a photo. Nova Forms cleans the paper to pure white, cuts away the empty space, and saves your signature at the size and KB your form asks for. It is made on your device, so nothing is uploaded.

How it works

  1. Sign on white paper

    Use a black or blue pen on plain white paper. Take the photo from straight above, in good light.

  2. Pick the signature

    Choose the photo, then drag the corners so that only your signature is inside the box. Just the paper finds the sheet for you.

  3. Make it clean

    Check the clean signature. Make it darker or lighter, and thicker if the lines are thin. Cut away the empty paper if you like.

  4. Set the size and save

    Tap a quick setting such as IBPS signature, or pick the pixels and KB yourself. Tap Make my signature, then Save file.

Why use this tool

A clean white background

The shade of the paper and soft shadows are taken out, so the paper turns white. Your signature stays dark.

Darker, lighter or thicker

One slider makes the writing darker or lighter, and one button makes thin lines thicker. You see the result at once.

Cut to fit

The empty paper around your signature is cut away, so the signature fills the size your form wants.

Exact pixels and KB

Pick 140 × 60 or 4 × 2 cm, or type your own size, and set the smallest and largest KB.

Quick settings

IBPS signature, SSC signature, and NEET and JEE signature, each one tap.

Private

Your signature is opened, cleaned and saved in your browser, on your own device. It is not sent to a server.

Tips for a good signature picture

Questions

Is this signature resizer free?
Yes. It is free to use, with no watermark and no account.
What size should my signature be?
It depends on the form. The IBPS notices we know of ask for 140 × 60 pixels, as a JPG of 10 to 20 KB, and SSC asks for 4 × 2 cm, as a JPG of 10 to 20 KB. Always read your own notice.
How do I make my signature under 20 KB?
Choose the photo of your signature, tap Next, then tap Under 20 KB (or a quick setting such as IBPS signature) and tap Make my signature.
My signature looks thin or grey. What do I do?
Move the slider towards Darker, or tap Thicker. Both change the picture at once, so you can see the result before you save.
What does Cut away the empty paper do?
It cuts the picture to the writing, so the signature is as big as it can be in the size your form wants. Switch it off if you want to keep the empty space around it.
My photo has a table or a hand in it. Is that a problem?
No. Drag the corners of the box so that only your signature is inside it, or tap Just the paper to find the sheet. The rest is left out.
Can I keep the background see-through?
No. The picture is saved as a JPG, which has no see-through parts, so the background is white. That is what forms ask for.
Is my signature uploaded?
No. The photo is opened, cleaned and saved in your browser, on your own device. Nothing is sent to a server.
