Frequently Asked Questions
Frequently asked questions about PAN card photo and signature resizing.
What are the exact photo specifications for NSDL and UTIITSL PAN Card applications?
Both Protean (NSDL e-Gov) and UTIITSL require applicant passport photographs to measure exactly 213 × 213 pixels (or 3.5 × 2.5 cm at 300 DPI). The file format must be JPEG/JPG with true colors, and the file size must strictly not exceed 30 KB (minimum 10 KB).
What are the exact signature specifications for PAN Card Form 49A / 49AA?
The applicant signature or left thumb impression must measure exactly 400 × 200 pixels (2:1 aspect ratio) at 600 DPI resolution. The file size must be strictly under 60 KB (minimum 10 KB). The ink should be dark black or dark blue on clean white paper.
Why does the NSDL portal reject my photo with "Resolution must be 300 DPI"?
Standard image editors only set pixel dimensions (213×213) but leave the internal JFIF resolution header at 72 DPI (web default) or uncalibrated. NSDL’s server software inspects the byte-level JFIF header. Kagazo automatically writes the binary 300 DPI (0x012C) marker for photos and 600 DPI (0x0258) marker for signatures, guaranteeing immediate portal acceptance.
How does the B&W Ink Clarity Booster work for phone camera photos of signatures?
When you photograph a signature with a smartphone, paper creases, yellow room lighting, and shadows often cause portal rejection. Our in-browser Otsu thresholding engine separates dark pen strokes from the background, converting shadows into pure white while intensifying ink lines to deep black.
Are my biometric photos and signatures uploaded to any server?
Never. Kagazo processes all image crops, DPI header injections, and quantization entirely in your browser’s volatile RAM via WebAssembly. Zero bytes leave your device, ensuring total privacy for your identity documents.
