How to resize a signature to 10 KB

  1. Sign on white paper with dark ink. Use a black or dark blue pen on plain white paper. Avoid ruled or textured paper as it compresses poorly.
  2. Photograph or scan just the signature. Crop tightly so only the signature is visible. No surrounding paper, no fingers, no shadows.
  3. Drop the image here. Select or drag your signature file. The 10 KB target is preset.
  4. Click Resize Image. The tool compresses to under 10 KB while keeping the strokes as sharp as possible. Processing happens on your device.
  5. Download and upload to the form. Save the result and submit it to your application portal.

Which forms need a signature under 10 KB

The 10 KB signature limit is enforced by some of the strictest government portals in India. UPSC, SSC, several state PSC portals, and banking recruitment boards (IBPS, SBI PO) use this limit to keep storage minimal across lakhs of applicants.

At 10 KB your signature must be tightly cropped with no surrounding paper visible. A signature photographed on a full A4 sheet will use most of the 10 KB budget encoding blank paper, leaving the actual strokes blurry and blocky.

The best approach is to sign on clean white paper with a dark pen, photograph or scan just the signature area, and run it through this tool. Black ink on white paper compresses extremely well, so even at 10 KB the strokes remain sharp and legible.

Frequently asked questions

How do I compress my signature to 10 KB?

Crop your signature image to remove all blank space, drop it into the tool on this page, and click Resize Image. The 10 KB target is preset. The tool finds the best quality that fits and shows you the real file size.

My signature is unreadable at 10 KB. What should I do?

The most common cause is too much blank space around the signature. Crop until the signature fills the frame. Also try scanning instead of photographing — phone photos add shadows and uneven lighting that eat into the file size budget.

What pixel dimensions should my signature be?

Most portals asking for 10 KB signatures also specify dimensions like 140x60 pixels or 150x70 pixels. Check your form's instructions. Set the pixel dimensions first using the image resizer, then use this page for the 10 KB limit.

Is my signature safe? Is it uploaded anywhere?

No. All compression happens in your browser. Your signature image never leaves your device, which matters since signatures are sensitive personal data.
