Official PAN Card Signature Size, Format, Pixels & KB

The signature image requirements are strict, and they differ slightly for NSDL (Protean) and UTI portals. Here are the updated rules:

Portal Accepted Format Dimensions KB Limit DPI Color
NSDL (Protean) JPG 4.5 x 2 cm
(~354×157 px at 200 DPI)
< 50 KB 200 Color
UTI JPG, JPEG, PNG 400 x 200 px (at 600 DPI) < 60 KB 600 Black & White Preferred

How to Create a Perfect PAN Card Signature Image

  1. Use a plain white paper and a thick black or blue pen for your signature.
  2. Take a clear photo or scan the signature, making sure there are no shadows or extra borders.
  3. Cropping is important—only the signature, no blank space around it.
  4. Resize the image to the required pixels or centimeters using an online tool like PANResizer.com.
  5. Compress your signature image so it is under the KB limit.
  6. Save as JPG/JPEG (or PNG for UTI), and use color for NSDL, black & white for UTI.

Why Are PAN Card Signature Size & KB Limits Important?

  • Wrong dimensions or file size can cause rejection and delay your PAN card.
  • System checks will block files with extra borders, low DPI, or high KB.
  • For best results, use recommended DPI and color format for each portal.
