Free Signature Maker for Passport Seva

Crop and resize your signature to the 140×60mm wide rectangle Passport Seva requires. Outputs JPEG under 100 KB on a white background. Free. No account. Runs in your browser.

How It Works

The tool takes any photo or scan of your signature and crops it to the 140×60mm wide-rectangle aspect ratio Passport Seva expects (and most Indian government portals use). It then resizes to a sensible pixel resolution, flattens the background to white, and compresses to JPEG under 100 KB — the upper file-size limit on the Passport Seva signature upload field.

Everything runs in your browser via Canvas. The signature image is never uploaded to a server.

Passport Seva Signature Specifications
  • Aspect ratio: 140 × 60 mm (a wide rectangle, not a square)
  • File format: JPEG only
  • File size: under 100 KB
  • Background: plain white or off-white
  • Ink: dark blue or black only (no pencil, no light colors)
  • Composition: signature centered in frame with margin, not touching the edges
Common Upload Errors and Fixes
  • "Invalid aspect ratio": the image is square or too tall — Passport Seva requires the wide 140:60 ratio. Re-crop to a wide rectangle.
  • "File too large": the JPEG exceeds 100 KB. Lower the JPEG quality or reduce pixel dimensions.
  • "Background not white": shadows or off-white paper — brighten the image or use a phone scanner app with auto-background flattening.
  • Signature too faint: typically pencil or a worn ballpoint pen. Re-sign with a fresh dark blue or black ballpoint or gel pen.
Frequently Asked Questions

What size signature does Passport Seva require?

140 × 60 mm aspect ratio (wide rectangle), saved as a JPEG under 100 KB, with a white or off-white background and dark blue or black ink. This is a different specification from your passport photo (630×810 pixels at 35×45 mm).

Can I sign on white paper and take a photo?

Yes. Sign on plain white paper with a dark blue or black pen, then photograph it from directly above with good even lighting and no shadows. The photo will need cropping to a wide rectangle and may need brightness adjustment to make the background pure white. This tool handles both in one step.

What pen color is acceptable for an Indian passport signature?

Dark blue or black ink only. Pencil signatures, gel pens with non-standard colors, and faint signatures are common rejection reasons. Ballpoint and rollerball pens both work; avoid felt-tip pens that bleed on photo capture.

Should I scan or photograph my signature?

A phone photograph in good lighting works fine and is faster than finding a scanner. If you have access to a flatbed scanner, that produces the cleanest background with no shadows or perspective distortion. Either way, the file needs cropping to a wide rectangle and resizing under 100 KB — both of which this tool handles automatically.
