NSDL Signature Guidelines and Specifications

For submitting digital PAN card applications through the NSDL (Protean) e-Governance portal, signature files must adhere to strict dimensional and size constraints. The required dimensions are 4.5 cm in width and 2.0 cm in height, scanned at 200 DPI, with a file size limit capped strictly at 50 KB.

Because many individuals have a long running handwriting style, trying to fit a wide signature into a small box often cuts off the first or last letters. Smart CSC Tool features an advanced Auto-Fit Engine that scales down wide dimensions proportionally and places the entire signature neatly inside the standard NSDL frame.

Auto-Enhance and Clean Processing

Paper signatures photographed via mobile phones usually contain gray shadows or uneven lighting. Checking the "Auto-Enhance" option triggers an automatic threshold filter that eliminates background smudges, resulting in high-contrast black ink over a pure white background.

100% Privacy Guaranteed: All signature processing happens entirely within your web browser. We never upload, save, or retain your private documents on our servers.
