Portugal passport photo size & rules
Portugal uses the 35x45mm format for passports and the Citizen Card (Cartao de Cidadao), equal to 413x531 pixels at 300 dpi. Portuguese requirements follow the ICAO biometric standard, so the face should occupy about 70-80% of the frame, with the head measuring roughly 32-36mm from chin to crown. Portuguese passports and Citizen Cards are often processed together at Loja do Cidadao and IRN offices, where the photo may be captured live, but supplied 35x45mm photos following the biometric proportions are still used in many cases.
The background should be plain and light, either white or a uniform light grey, without shadow or texture. Face the camera directly with a neutral expression and mouth closed, both eyes open and clearly visible, and the head straight rather than tilted. Portugal asks for the whole face to be shown, uncovered from the forehead to the chin, in sharp focus with natural skin tones. Glasses should be removed where possible; if worn, there must be no reflection or tinted lenses. Head coverings are only accepted for religious reasons, provided the full face remains visible. The photo must be recent.
Pixohub formats your Portuguese passport or Citizen Card photo to 413x531 pixels following the biometric standard directly in your browser, so nothing is uploaded and your image stays private on your own device, and the tool is free. Requirements from the IRN and Portuguese consulates are updated over time, and the live-capture process differs from supplied photos. Always confirm the current official specifications on the relevant government website before printing or submitting your photo.
