PAN Card Signature Resizer

NSDL rejects PAN card signatures that are even slightly outside the required specifications. Your signature must be exactly 4.5 x 2.0 cm (354 x 157 px at 200 DPI), under 20KB, in JPEG format with black ink on a clean white background. The most common rejection reason is that the signature touches or overlaps the border area - NSDL's parser enforces a minimum 5-pixel white margin on all sides. This tool resizes, crops, and compresses your scanned signature to pass both NSDL and UTIITSL validation on the first attempt.

How it works

Sign on plain white paper with black ink

Use a black ballpoint or gel pen on a plain white unruled sheet. Avoid lined paper, colored paper, or pencil. The signature should be your natural handwriting - identical to what appears on other government IDs.

Scan or photograph your signature

Use your phone camera in good lighting, holding the camera directly above the signature to avoid perspective distortion. A flatbed scanner at 200+ DPI produces the best results. Ensure the full signature is visible with some white space around it.

Upload, resize, and compress

Upload the scanned signature. The tool resizes it to exactly 354 x 157 px, ensuring your signature does not touch the edges (5px margin on all sides). Then compress to under 20KB and download the portal-ready JPEG.

Frequently asked questions

Why does NSDL reject my PAN card signature?

The top 3 rejection reasons are: (1) signature touches or overlaps the border area - NSDL requires a minimum 5-pixel white margin, (2) file size exceeds 20KB, and (3) wrong format - PNG or HEIC instead of JPEG. This tool addresses all three issues automatically.

Can I use a blue ink signature for PAN card?

While NSDL does not explicitly ban blue ink, their automated scanner performs better with high-contrast black ink on white background. Blue ink signatures sometimes appear faded or grey in scans, which can trigger the 'signature not clearly visible' rejection. Use black ink to be safe.

Should my PAN card signature match my Aadhaar signature?

Ideally, yes. NSDL cross-references signatures during KYC verification. While minor variations are acceptable (signatures naturally evolve over time), a completely different signature style may cause delays in PAN card processing or trigger manual verification.

Can I use a digital/mouse-drawn signature for PAN card?

NSDL prefers scanned handwritten signatures over digitally drawn ones. Digital signatures often have unnaturally smooth strokes and uniform thickness, which can look suspicious during manual review. Always sign on paper and scan for the best results.

What if my signature is very long and gets cut off at 354 pixels?

If your full signature does not fit within the 354x157 pixel frame, you have two options: (1) use a slightly more compact version of your signature, or (2) sign on a wider area and let the resizer scale it down proportionally. The tool will maintain your signature's aspect ratio while fitting it within the required dimensions.
