Resize Signature to 10 KB – 20 KB Online Free (Exam Form Signature Resizer)
Turn a photo of your signature into a clean JPG between 10 and 20 KB. It is set to 140 × 60 pixels with a white border, so nothing gets cut off — change the size if your form asks for something else.
How to resize a signature to 10–20 KB
Add the signature image
Select or drop the photo or scan of your signature, cropped close to the signature.
Check the size
The tool is set to 10–15 KB and 140 × 60 pixels. For a size in cm (for example 6 × 2 cm), choose cm and type it.
Resize and download
Press Resize to KB. You see the final KB and pixel size before you upload it.
Everyday uses
- Bank exam forms – IBPS notifications have asked for a 140 × 60 pixel signature of 10–20 KB.
- SSC forms – recent notifications ask for a 10–20 KB JPEG of about 6.0 × 2.0 cm.
- Scholarship and admission forms – signature uploads with a KB limit.
- Account opening and KYC forms – when a portal asks for a small signature image.
Good to know
The signature is fitted inside the size with a white border, so the whole signature is kept even if its shape is different. It is then saved as a JPG at the highest quality under the maximum. If it is still below the minimum of 10 KB, a harmless padding block is added inside the JPG so the file meets the minimum without changing how it looks.
We aim for 15 KB by default: that is inside 10–20 KB whether a portal counts 1 KB as 1,000 or 1,024 bytes.
Private by design. Resize Signature to 10–20 KB works inside your browser. Your file is processed on your device and is not uploaded to our server.
How to photograph and crop your signature
- Sign on plain white paper with the pen your form asks for (usually black or dark blue ink).
- Sign a little larger than usual, in a space two to three times as wide as it is tall.
- Take the photo in daylight, holding the phone straight above the paper. Avoid the shadow of your hand or phone, and turn off the flash to avoid glare.
- Crop close around the signature with Crop Image, leaving a small white margin.
- Add the cropped image here and press Resize to KB.
- Open the result and zoom in: the signature must be clear, dark and not cut off.

Limits to know before you start
- The tool does not clean up shadows or grey paper. A dull photo stays dull, so retake it in better light if needed.
- The output is JPG, which these forms ask for. Transparent areas become white.
- Very small sizes (like 140 × 60 pixels) only show a clear signature if it fills most of the image, so crop tightly first.
If something goes wrong
The signature looks cut off. This page uses “Fit with white border”, which keeps the whole signature. If you changed it to “Crop to fill”, switch back.
The portal says the file is too small. Keep the minimum at 10 KB (or the minimum your form gives) and resize again.
The signature looks faint. Sign again with a darker pen and photograph it in daylight without shadows.
Resize Signature to 10–20 KB – questions
How do I resize my signature to 10–20 KB?
Add the signature image and press Resize to KB. The tool is set to 10–15 KB at 140 × 60 pixels, so the result is a JPG inside the 10–20 KB range.
What size is 140 × 60 pixels in cm?
At 200 DPI it is about 1.8 × 0.8 cm; at 300 DPI about 1.2 × 0.5 cm. If your form gives a size in cm (for example 6 × 2 cm), choose cm, type the width and height and set the DPI.
Why is there a white border around my signature?
Your signature has a different shape from 140 × 60, so it is fitted inside with a white border instead of being cut. Crop the photo tightly first so the signature fills more of the space.
The portal says the file is too small. What do I do?
Keep the minimum at 10 KB. If the image is very simple, the tool adds a harmless padding block inside the JPG so it reaches the minimum without changing how it looks.
Is my signature uploaded?
No. It is processed in your browser and stays on your device.
