How It Works

Passport Seva's published guidance calls for a rectangular signature image under 100 KB but does not publish an exact pixel size. This tool uses a practical 3:1 layout and exports a 600×200 JPEG, with the signature centered on white and compressed below that limit. Confirm the current prompt shown for your application before uploading.

Formatting runs in your browser via Canvas without an operational image upload. Troubleshooting replay may include canvas pixels as disclosed in our Privacy Policy.

Passport Seva guidance and this tool’s output
  • Published shape: rectangular, not square
  • Tool output: 600 × 200 pixels (a practical 3:1 default, not a published mandatory size)
  • 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 — re-crop it to a clean wide rectangle and follow the current portal prompt.
  • "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?

Passport Seva's published guidance specifies a rectangular signature image under 100 KB but does not publish an exact pixel dimension. This tool exports a 600×200 JPEG as a practical wide default. Follow the current prompt shown for your application if it states a different limit.

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.
