How to scan and crop a signature for a PAN card with a white background

Sign and capture on clean paper

1. Use clean, uncreased white paper and sign in the manner and ink color requested by the current application.
2. Use a flatbed scanner if available. Place the paper flat and scan in color or grayscale at a resolution sufficient to keep thin strokes clear.
3. If using a phone camera, put the paper on a flat surface in bright, even light. Hold the phone parallel to the page and avoid your hand or phone casting a shadow.
4. Keep the whole signature, including the first and last strokes, within the captured frame.

Crop without damaging the signature

Straighten a tilted scan, then crop away unused paper while leaving a narrow white margin around the signature. Do not crop too tightly: the pen may extend farther than it first appears, and a little space makes the result easier to review. Keep the aspect ratio requested by the current portal; do not distort the signature to fill a rectangular box.

Use a PAN card signature resizerto adjust the crop and export a suitable JPEG. Confirm the dimensions and size from the current application rather than assuming an old NSDL or UTIITSL preset is still valid.

Keep the background white and the ink visible

Avoid colored paper, patterned surfaces, desk edges, and high-contrast shadows. If the paper appears gray because of uneven lighting, make a better capture before adjusting levels. Overexposure can erase faint ink; over-darkening can turn the background gray and thicken the strokes. Review the final image against a white screen and zoom in to check that every mark is intact.

Do not use a filter that removes specks by also removing dots or thin lines from the handwritten signature. The goal is a faithful, legible image of the signed paper—not a digitally recreated signature.
