Signature Resizer

Fit your signature into the required pixel and KB limits

Sign a white paper with a black or blue pen, scan or photograph it, and upload. Crop the tool to the signature area. Then set the target dimensions, many Indian exam forms ask for 140 x 60 pixels or similar, and the tool resizes the canvas. You can also compress it to a specific KB size. The output is a transparent PNG or a white-background JPEG, ready to paste into the form. The key is getting the signature dark and clear on a plain white background for best results.

The forms that ask for a signature image

• IBPS PO/Clerk, SBI, SSC, UPSC, and almost every competitive exam application. They want a signature image of specific pixel dimensions and under 20 KB or 50 KB.
• Online e-signature for Aadhaar-linked documents where you can upload a signature image instead of drawing with a mouse.
• Company HR portals during onboarding ask for a signature image for ID cards or digital documents.

Tip: Use a thick black pen, sign on a clean white paper, and photograph it in daylight without shadows. The tool's threshold adjustment can turn the background pure white and the signature solid black, which compresses well and looks crisp.

Frequently Asked Questions

My signature looks pixelated after resizing. How to fix?

Start with a high-resolution scan or photo. If the original is too small, enlarging it will pixelate. Take a fresh, larger image and resize down instead of up.

Can it make the background transparent?

Yes, the tool can output a PNG with a transparent background, which some forms accept. If the form demands JPEG, it will fill the background white.

What is the exact signature size required for SSC and IBPS forms?

Most SSC and IBPS forms ask for a signature around 140x60 pixels and 10-20 KB. UPSC photo specifications differ (350x350 px, 20-300 KB). Always check the specific notification since exact limits can vary by exam year.

Why does my resized signature not fit within the KB range?

This usually happens with very low-resolution or very high-detail originals. Try a cleaner scan with a plain white background and less shading, which compresses more predictably into the target KB range.

Is this tool free and does it store my signature image?

Yes, it's completely free and processes everything locally in your browser. Your signature image is never uploaded or stored on a server, which matters since a signature is sensitive personal data.
