Resize Signature Online (140×60, 10–20KB)
Online forms ask for a signature image of an exact size, most often 140 × 60 pixels and 10–20 KB. Upload a photo or scan of your signature and this tool fits it onto a clean white canvas of the size you choose, keeps the file within your KB range, and gives you a JPG to download.

How to resize your signature
- Sign on plain white paper with a black (or the required) ink pen.
- Take a clear photo in good light, or scan it, and crop close around the signature on your phone.
- Upload it above. Change the width, height and KB boxes if your form uses a different size.
- Download the JPG and upload it on your form.
Common signature sizes
IBPS bank exam guidelines use 140 × 60 pixels and 10–20 KB, which is why that is the default here. Other recruiting bodies and universities use different sizes, so read the photo and signature section of your official notification and enter those numbers.
Tips for a clean signature image
- Use thick, dark ink so the signature stays readable at a small size.
- Avoid lined or coloured paper and shadows from your hand or phone.
- Do not sign in capital letters if your form forbids it (IBPS does).
- Crop extra white space before uploading so the signature fills more of the frame.
Frequently Asked Questions
What is the standard signature size for online forms?
There is no single standard. 140 × 60 pixels and 10–20 KB is common for bank exams (IBPS); always follow your own form's notification.
Will my signature be stretched?
No. The signature is scaled to fit inside the frame and the remaining space is filled with white, so it never gets distorted.
My file is smaller than the minimum KB. What does the tool do?
Small images like a 140 × 60 signature can come out under the minimum even at the highest quality. The tool then adds harmless comment data inside the JPG so the file reaches the allowed range without changing how the image looks.
Are my photo and signature uploaded anywhere?
No. Resizing and compression happen inside your browser. Your files never leave your device.
Can I resize a signature on my phone?
Yes. Open this page in your mobile browser, take or choose the photo, and download the result. No app is needed.
