04What we fix
What we fix for free, and what AI fixes
Fixed for free
- Background. Replaced with the one this document asks for: plain white background.
- Head tilt. Straightened if the head leans slightly to one side.
- Frame. Exactly 30 × 40 mm, by the document’s rules.
- A light shadow on one side of the face. Gently brightened.
- File and print sheet. A file to the document’s rules and a 10 × 15 or A4 sheet to print.
What can't be fixed for free, AI correction fixes
- Hard shadows and uneven light on the face.
- A smile, raised brows or a half-open mouth. Cropping keeps the face it was given.
- Too few pixels. If the original is smaller than 354 × 472 px, enlarging it only blurs the face.
- Clothing and pose. Shoulders out of frame, body turned away from the camera.
Glare on the lenses. Take the glasses off or turn away from the light source and shoot again.

06Good to know
Brazil-specific things to know
- Brazil's identity card is a state document: the photograph is taken at the identification institute at the appointment, so adults usually bring no 3 × 4 print — only children of 0–2 and posts without biometric capture ask for one.
- The states word the rules differently: Paraná bans glasses and asks for the forehead showing with no fringe, Santa Catarina asks to avoid white clothing and previous-ID photographs.
- Lasting facial paintings of specific ethnic groups and ear gauges are named as allowed in the photograph; removable facial paint is not.

What the source confirms
- Polícia Científica de Santa Catarina (Portaria 043/2024/PCI), «Fotografias»: a 3 × 4 photograph is no longer required for the issue of the identity card, except for children of 0 to 2 years, whose photographs are presented by the person present at the biographic and biometric registration in print (3 × 4) or digital form; at identification posts without digital biometric capture the 3 × 4 photograph remains compulsory in all cases.
- Same page, the photographs: in colour, recent (90 days) and identical, allowing the perfect current identification of the person, without a date, on a white background, without retouching (printed on matte paper), with no printed, dark, shaded, dashed or dotted background; the bust of the applicant (head, neck, both ears and the upper chest) in a frontal position, in the 3 × 4 size set by Decree 9.278/2018; a neutral expression and closed lips; no facial paint that interferes with the view of the face, except permanent cultural paint of specific ethnic groups.
- Same page, clothing and coverings: avoid white clothing; except for religious habits, hair loss due to pathologies, medical treatment or visual impairment, the face must not be covered by hair, a veil or dark glasses, nor a hat, cap, bandana or other object covering the head; no objects or prints that advocate drugs, racism, violence or political slogans; women should not wear a top, dress or strapless blouse that gives the false impression of no clothing, men no printed T-shirts with advertising or inappropriate slogans and no tank tops; religious orientations are respected (a habit, a turban and others that leave the face visible); photographs of the previous identity card are not accepted.
- Polícia Civil do Paraná, «Informações sobre a CIN», photograph: it should be as recent as possible, so it is captured by the Identification Institute at the in-person appointment, free of charge; for an online request the applicant captures the photograph when sending it; to meet the ICAO standards under Federal Decree 10.977/22 the photograph shows the face, head, neck, both ears and the upper chest in a frontal position in the proportion of 3 × 4 cm, on a white background without reflections, patterns, stains or shadows, the hair behind the shoulders and ears with the forehead showing (no fringe), a neutral expression and closed lips.
- Same Paraná page, prohibited items and exceptions: earrings, piercings, removable facial paint, necklaces, glasses, coloured contact lenses, hats, caps, berets, bands, scarves, beanies, hoods or any other item that hinders the identification of the face and the neck outline; ear gauges, as a continuously worn accessory, may be kept; dark glasses are optional only in total visual impairment; a headscarf is allowed for a pathology, medical treatment or religious habit if neutral and light in colour and the face and the neck outline are visible; lasting facial paintings of specific ethnic groups are allowed.
