Almost every rejected ID photo fails on something that can be measured before you submit it: the head is too tall, the eyes sit too low, the background is not plain enough. This page explains what IDShot checks, what each rule means, and what to do when a check goes yellow.
Because the rules are numeric and a photo taken by eye almost never hits them. Head height is usually specified as a range in millimetres or as a percentage of the frame; the eye line has to fall inside a band measured from the bottom edge; the background has to be a specific colour, plain and shadow-free. Miss any one and the photo is returned. All three are measurable before you submit, which is what the checker does.
What does head height actually mean?
The distance from the top of the head - the crown, including hair, but not hair that sticks up loosely - down to the bottom of the chin. A Schengen visa photo, for example, is 35 by 45 mm with the head between 32 and 36 mm. US rules are expressed as a proportion instead: the head should be roughly 50 to 69 percent of the image height. IDShot draws crown, eye line and chin guides with live measurements so you can see where you are inside the allowed band.
What background colour do I need?
It depends on the document, which is why the preset carries it. Plain white is the most common; Schengen countries usually want light grey, some authorities specify off-white, cream or light blue. One tap replaces the background with the required colour, and the edges around hair stay natural rather than being cut out with a hard line.
Can I just take the photo against my wall?
Yes, and that is the intended use. Stand about a metre and a half from a reasonably plain surface, face the window or another soft light source so there are no hard shadows behind you, and let the camera guidance tell you when the framing is right. The background is replaced afterwards; the lighting on your face is the part the wall cannot fix.
Does the app edit my face?
No, deliberately. Authorities reject photos that have been retouched, and biometric systems compare the photo against a live face, so a smoothed or reshaped image is a liability. IDShot corrects light and colour and replaces the background. It never softens skin, slims a face or changes features.
What does the checker actually measure?
Fourteen things: head size, eye height, centering, tilt, turn, open eyes, closed mouth, hands near the face, lighting, shadows, sharpness, exposure, colour and background. Each one shows the measured value, the range the document allows, and what to change. A score tells you when everything is inside its range.
A check is yellow rather than red. Can I still submit?
Yellow means the value is close to the edge of what the rules allow, or that the app cannot be certain - for instance a background that is plain but slightly uneven, or a head height right at the top of the band. It is a warning, not a failure. If you can retake or re-crop to move it clear, do; if not, the linked official page is the place to check the authority's own wording.
Can I wear glasses, a head covering or a uniform?
This varies by country and by document, so it is one of the things the preset links out for. As a general rule: most authorities now refuse glasses in passport photos, religious head coverings are usually permitted provided the full face from the bottom of the chin to the top of the forehead is visible, and uniforms are usually not allowed. The app checks the geometry and lighting - the wording on the official page governs the rest.
Why does the export have a file-size limit?
Because upload portals do. The US DV Lottery accepts a 600 by 600 pixel square within 240 KB; India Passport Seva expects 630 by 810; Singapore ICA expects 400 by 514. IDShot exports at the exact pixel size and tunes the JPEG so the file lands inside the portal's window without visible quality loss, tags the DPI and colour space, and strips location and camera metadata.
How do I print the photo at the right size?
Use a print sheet rather than printing the single image. Export a 4 by 6, 5 by 7, A4 or Letter sheet with cut marks and print it at 100 percent scale - no "fit to page", which is what usually shrinks a photo by a few percent and makes the head too small. A family sheet puts several people on one print.
Do my photos get uploaded?
No. Face and hairline detection and background removal run on the device with Apple's Vision framework. There is no account, no ads and no tracking, and photos leave the device only when you export or share them yourself.
Which documents and countries are covered?
Over 500 presets across 116 countries - passports, visas and e-Visas, national ID cards, driving licences, residence permits, work and study permits, citizenship applications, and exam or professional cards. That includes the US passport and DV Lottery, UK HMPO, the Schengen area, Canada, Australia, India Passport Seva, China, Japan, Korea and Singapore ICA.
What is free and what does the purchase unlock?
Everything up to the export is free: the camera with live guidance, auto-crop and manual adjustment, background replacement, the full checker and every preset. One purchase unlocks saving, sharing, copying and printing the finished photo - permanently, on iPhone, iPad and Mac, with no subscription.
Can IDShot guarantee my application will be accepted?
No, and no app can. IDShot measures what can be measured against the authority's published rules. The decision belongs to the issuing authority, and each preset links to their official page so you can check their current wording before you submit.
Get IDShot: Passport & Visa Photo
Passport, visa and ID photos cropped to the exact rules of 500+ document presets and checked before you submit - all processed on the device.
When you already have a picture you like and only the geometry is wrong.
Choose the document preset, then open the photo from your library or from Files.
Run Auto Crop & Level - face and hairline detection place the head inside the allowed band and level the eyes.
Check the crown, eye line and chin guides against the live measurements shown beside them.
Nudge the crop in half-millimetre steps or straighten by tenths of a degree if a value sits near the edge of its range.
Replace the background with the colour the preset requires.
The photo has to have enough resolution to crop into. A picture where the face is small in the frame will not survive being cropped to a passport format.
Head too large or too small: re-crop rather than retake - Auto Crop will place it, and the measurement tells you how far off you were.
Eyes too low or too high: straighten first, then move the crop vertically; the eye line is measured from the bottom edge.
Shadow on the background: move further from the wall and turn towards the light. Background replacement fixes colour, not a shadow that falls across your face.
Reflections or glare on glasses: take the glasses off. Most authorities now require it anyway.
Expression: mouth closed, no smile, both eyes fully open, head straight on rather than turned.
If a check stays yellow after two attempts, read the rule it cites on the official page - some authorities are stricter in wording than the numeric range suggests.
Printing is where a correct photo most often comes out the wrong size.
Open Export and choose Print Sheet.
Pick the paper the shop uses - 4 by 6 and 5 by 7 are the usual photo sizes; A4 and Letter suit a home printer.
Save the sheet as a file and order it as a normal photo print, or print it yourself.
Make sure scaling is set to 100 percent, actual size, with any "fit to page" or "borderless fill" option turned off.
Cut along the marks once it is printed.
If the shop's machine crops to fill the paper, the photo comes back a few percent small and the head height fails. Ask for no cropping, or use a sheet that matches their paper exactly.
Take and finish each person's photo separately, against the same wall and the same light if you can.
Check each one against its own document preset - a child's passport often has different rules from an adult's.
Open Export, choose Print Sheet, and add the finished photos to one sheet.
Print at 100 percent scale and cut along the marks.
Infants are the exception to most guidance: many authorities relax the expression and eye rules for babies, and the official page for the document is the place to confirm it.
