Whether applying for a fresh Permanent Account Number (PAN) card or requesting name, photo, or signature corrections, applicants on NSDL (Protean) and UTIITSL portals frequently encounter upload errors such as "Invalid Image Resolution or File Size Exceeded".
Both NSDL and UTIITSL mandate strict physical dimensions, 200 DPI optical resolution, and file size limits under 50KB. This guide walks you through the exact technical requirements and shows you how to prepare portal-ready images in under two minutes.

Step-by-Step: Formatting PAN Card Documents
1. Capture a clear photo of your face against a white wall and sign cleanly on blank white paper.
2. Open UtilityHub's Photo & Signature Resizer.
3. Upload your photo and choose the "PAN Card Photo (2.5 x 3.5 cm)" preset. Set the target size to 45KB.
4. Click "Download Resized Image".
5. Upload your signature image, choose the "PAN Card Signature" preset, and download.
6. For your Aadhaar or address proof PDF, if the file exceeds 300KB, use UtilityHub's PDF Compressor to reduce it under 300KB without blurring text.
Rejection Prevention Tips
- High Contrast Signature: Use a black ballpoint pen on plain paper. Never crop signatures from notebook paper with printed lines.
- Tight Framing: Ensure the photo frame contains only the applicant's head, ears, and neck. Do not leave wide empty margins.
- Complete Confidentiality: Because PAN applications involve sensitive financial identity, UtilityHub processes all files entirely on your device with zero server storage.
