Online PAN card applications ask for a small colour photo with fixed dimensions and a low file size. This tool resizes your photo to 2.5 x 3.5 cm so it matches the PAN card photo box.
The photo box is 2.5 x 3.5 cm. Online portals also set a small maximum file size, so compress the photo if the upload is rejected.
No. The tool runs in your browser, so the image stays on your phone or computer.
