Signature Resizer: Resize Signature to 10–20 KB

Take a photo of your signature on white paper and turn it into a clean, sharp JPG at the exact pixel and KB size your form asks for, for example 140 × 60 pixels at 10–20 KB.

What does the form ask for?

Or paste the rules from your notification

For example: “Signature: 140 x 60 pixels, file size 10 KB to 20 KB, JPG”. Paste one document at a time.

You will get a 400 × 150 pixel JPG of at most 20 KB. The form has no fixed pixel size, so we use a good default. You can change it.We aim for 0 to 20,000 bytes. This passes whether the form counts 1 KB as 1,000 or 1,024 bytes.

Add your signature

Your image stays on this device. It is never uploaded.

Already have a file? Check it before you upload

See if your file follows the rules above before you upload it. Most forms don’t tell you what is wrong.

How to resize your signature

  • Sign with a black pen on plain white paper and take a photo in daylight, holding the phone straight above the page.
  • Add the photo to the tool. It is set to “Any form: Signature under 20 KB”. Type your form’s width, height and minimum KB if it gives them.
  • Keep “Clean up the paper” on. It turns grey or yellow paper white and makes the ink darker, like a scan.
  • Zoom and drag so the signature fills the box with a little white space around it, then download.

Signature sizes for common exams

IBPS and SBI: 140 × 60 pixels, 10–20 KB. UPSC: three signatures one below the other, 350 × 350 to 500 × 500 pixels, 20–100 KB. NTA (JEE Main, NEET UG, CUET): 4–30 KB. Always compare with your own notification, since rules change between years.

Why signatures get rejected

  • Signed in capital letters. IBPS, SBI and many other bodies do not accept a signature in block capitals.
  • Too faint. Blue ballpoint on grey paper can almost disappear after compression. Use a black pen and keep clean-up on.
  • Too small in KB. A signature is mostly white, so files often come out under the 10 KB minimum. The tool pads the file to reach the minimum without changing the image.
  • Signature does not match. The signature you upload must match the one you make at the exam centre, so use your normal signature.

Questions

How do I resize my signature to 140 × 60 pixels?

Type 140 in width and 60 in height (or choose “IBPS & SBI: Signature” in the list), add the photo of your signature and fit it into the frame. The download is exactly 140 × 60 pixels.

Can I make my signature background white?

Yes. “Clean up the paper” makes the paper white and the ink darker. It works best with a black pen on plain paper photographed in daylight.

Can I draw my signature on the screen instead?

Not in this tool, and most exam bodies want a signature written on paper with a pen and then scanned or photographed.
