For DGIP Online e-Passport renewal portals, NADRA Pak-ID mobile/web uploads, and visa applications, a plain white background is required. Some regional passport counters still accept light blue backgrounds for physical paper forms, but white is universally accepted across all online portals.
DGIP and NADRA online portals typically require JPEG images under 1 MB (and certain public service commission portals like FPSC/PPSC require under 30 KB or 50 KB). You can pair this tool with our Compress to 50KB or Compress to 20KB utility if needed.
Eyeglasses should be removed to prevent flash reflection on the lenses. Religious headwear (such as a hijab or cap) is permitted provided the entire facial oval from the bottom of the chin to the top of the forehead and both cheekbones remain unobstructed.
This tool crops and scales your portrait to exact 35 × 45 mm (413 × 531 px) biometric dimensions. If your photo was taken against a colored wall, run our Change Background tool first to set a solid white backdrop.
