ChatGPT and Gemini Passport Photo Prompts — and Whether Official Documents Accept the Result

Passport Photo Prompt for ChatGPT, Gemini and Nano Banana (2026)

These prompts work the same way in ChatGPT’s image editing, Gemini (Nano Banana), Grok and Copilot: upload your own photo first, then paste the prompt. The sentence that matters most is the one asking the model to keep your face; leave it out and the model will try to “improve” it. Stating the ratio is just as essential, because most tools return a square image by default, and when a square output is cropped to a 50×60 mm Turkish ID photo, the head ends up either too large or too small.

The prompts are in English, which some tools follow more consistently than other languages. A passport photo prompt for women or men is the same prompt: document rules do not change, so simply name what must stay as it is, such as long hair, a headscarf, a beard or glasses. If you don’t like the result, improving the source photo helps more than lengthening the prompt: flat light, no shadow on the face and a straight look at the camera. AI cannot fully correct the direction of the light or the angle of your head; how to get both right is in our guide to taking a passport photo with your phone.

Prompts don’t know millimetres: typing “50×60 mm” does not turn the output into millimetres, it only affects the aspect ratio. Millimetres, DPI and pixel dimensions are fixed at print or upload time. Sizes also differ by country — the US uses 2×2 in (51×51 mm, a square), the UK and Schengen countries 35×45 mm — so change the ratio in the prompt to match your document. A Turkish ID card, passport or driving licence photo is 50×60 mm (5×6 cm), which is 591×709 pixels at 300 DPI.

Will an AI Passport Photo Be Accepted for an ID, Passport or Visa?

Short answer: it depends on the authority, and the risk lies in your face being changed. Some authorities say so explicitly. The UK requires passport photos to be “unaltered by computer software” (GOV.UK passport photo rules), and for visa applications it states that the photo “must not be altered by computer software or through other means (for example, by adding a filter)” (GOV.UK visa photo guidance). In Türkiye, the Ministry of National Defence (MSB) says in its smart-card photo specification that the photo must not have been changed in any way with photo-editing software (MSB smart-card photo specification, in Turkish).

The biometric photo rules published by Türkiye’s civil registry (NVİ) contain no separate clause on AI; they ask for the size, a white background, head height and a neutral expression (NVİ biometric photo rules, in Turkish). But the whole point of a biometric document is recognising your face: the photo on an ID card and in a passport chip is compared with your live face by face-recognition systems. A photo in which the spacing of the eyes, the nose or the jawline has been redrawn no longer shows you exactly and can cause a matching problem, whichever country issues the document.

This risk is not theoretical. In a measurement on our own production pipeline, a wrong text prompt dropped face similarity (ArcFace) from the 0.92–0.98 band to 0.72–0.81 — in a generation that had only been asked to change the clothing. Chat-based tools don’t measure this similarity; if you don’t notice the change, nobody warns you. That is why the safe route for an official document is a method that either does not redraw the face at all, or measures the face it draws and discards anything below a threshold. For how the two standards differ, see biometric photo vs standard ID photo.

Check Your AI Passport Photo: The 6 Most Common Mistakes

The first mistake is the sneakiest, because it is hard to notice: the output looks like you, but it isn’t you. Open the original photo and the output side by side and go through the details one at a time. Square ratio and head size, on the other hand, stay invisible until you measure them; an ID photo cropped slightly too large or too small looks normal to the eye but does not meet the authority’s size.

vesikalik.com.tr’s free analysis checks the measurable part of these six points: framing and head ratio, background tone, shadows on the face, lighting balance, expression and sharpness are each reported separately as “pass”, “warning” or “fail”. For a more accurate result, upload your own original photo rather than the AI output; if something fails, the photo rejection reasons guide explains which rule failed and why.

Headshot Prompt for ChatGPT: When Is It Enough for CV, LinkedIn and Social Media?

If no authority can reject the photo, there are no rules either: for a CV, a LinkedIn profile, a company directory or social media, a headshot made with a prompt is often good enough. The size is up to you, and a light-grey or coloured background, a natural smile and a jacket are all fine. The one thing to watch is, again, that the face still looks like you; a profile photo introduces you too.

If you want to add a jacket or a suit, the detailed guide is on our AI corporate headshot page: how face-preserving generation works, how the clothing is chosen, and which flaws it fixes and which it does not are all explained there with measurements. For the right dimensions of a LinkedIn picture, see LinkedIn profile photo size.

If you are thinking of using the same photo on your CV and in an official application, prepare two separate frames. The smile and a coloured or textured background in the CV frame are reasons for rejection in an ID or passport application; the document frame needs a plain white, shadow-free background and a neutral expression with the mouth closed. A jacket or shirt is not a problem on its own, as long as the collar and shoulder line do not blend into the background.

Prompt vs a Face-Preserving Tool: What Is the Difference?

Instead of writing a prompt, you can upload your photo directly: the system first analyses it against the rules, then prepares the classic ID photo. In the classic output your face stays exactly as it is; the background is cleaned, the frame is cropped to the document’s size and the lighting is balanced. Next to it, an AI version is generated as a second option: the clothing and background are renewed with AI, your face is preserved and similarity is measured; an output below the threshold is never shown to you, and one that breaks a rule is not delivered. You decide which one to take.

If the authority explicitly asks for a photo not altered by software (as UK visas and passports do), follow the authority’s own instructions instead of using generative AI output. The sizes and rules for Turkish documents, one by one, are on the biometric photo sizes page, and the current price of the digital file and prints is on biometric photo prices.
