The job an ID photo tool actually has to do is narrower than it sounds. Your camera has already taken the picture. What remains is geometry: cropping to an exact physical size, and placing the head so that the chin-to-crown measurement falls inside the range your authority publishes. Get those right and most refusals never happen. That is what this does, using the specification for the specific document you name.
1. Choose the document, not just the size
This is the step that matters most, and the one generic croppers skip. Two countries can share an outer photo size and still demand visibly different crops: a 35 x 45 mm photo needs a 32–36 mm head for Germany and the Schengen standard, but 26–30 mm for the Netherlands. A photo made correctly for one is refused by the other. Pick your document from the document list and the head guides are set to that authority's published range, along with its background and glasses rules.
If you only know a measurement — a form said "35 x 45 mm", or a portal asked for "600 x 600 pixels" — use the size chart instead and pick the plain size.
2. Load your photo
Any ordinary photo taken from the front, in even light, works. The file is read locally; it is not uploaded anywhere. Practical guidance that improves the result more than any software setting: camera at eye height, about an arm and a half away, face lit from the front rather than the side, and stand an arm's length clear of the wall so your shadow does not fall on it.
3. Align, and adjust the background only if your authority allows it
Drag and zoom until the head sits between the guide lines and the face is centred. The guides are the authority's range, not a single target — 32 mm and 34 mm both pass a 32–36 mm rule, so there is no need to hit a figure exactly.
Background replacement is available, and runs on your device: a segmentation model separates you from what is behind you so the background can be made the plain white, off-white or light grey your document requires. It is genuinely useful when a real plain wall was not available. But it is off by default on the documents that forbid it, and those pages say so — U.S. online passport renewal rejects digitally replaced backgrounds outright, and South Korea and Nigeria have comparable bans. On those, photograph yourself against a real wall. Brightness and contrast controls exist for the same reason and carry the same warning.
4. Save a single photo, a printable sheet, or both
| Single photo | One image at the exact required size, at 300 or 600 DPI. This is what digital applications want — U.S. online renewal, the DS-160, most visa portals. Pixel dimensions and file-size limits are handled for you where the authority publishes them. |
|---|---|
| Printable sheet | The same photo tiled onto one 4 x 6 inch (or 10 x 15 cm) print with cut guides — six copies per sheet, which is more than any application needs. Take it to any shop that prints ordinary photos for a few cents, or print it at home. Country-by-country options are in the printing guides. |
What the tool checks — and what it cannot
Being straight about the limits is more useful than an approval-rate claim, so:
It does check: that the crop matches the required physical size and aspect ratio; that the head height falls in the published range for your document; that the output resolution is sufficient for print at that size; and, where the authority publishes numeric image rules — file size in KB, pixel bounds, eye-line position — that your file is inside them.
It does not check: whether your expression, hair, glasses glare or head covering satisfies a human reviewer; whether the photo is recent; whether the lighting is even enough. There is no face-landmark measurement of tilt or eye line, because the browser security policy this app is served under blocks the face-mesh models that would be needed. Rather than approximate it and be confidently wrong, the tool reports what it measured and leaves the rest to you — the rejection guide shows each fault side by side so you can judge them yourself.
It is also not affiliated with any government or passport authority, and it cannot pre-approve anything. Every document page quotes its specification with a link to the issuing authority so you can verify the numbers at source.
Frequently asked questions
What do I need to use it?
A browser and a photo of yourself taken from the front. No account, no app install, no payment. It works on phones as well as computers.
Does it take the photo for me?
You supply the photo — from your camera roll, or taken with your device camera. The tool does the crop, the head alignment to your document's published range, the size and DPI conversion, and optionally the background.
Which is better, the single photo or the sheet?
It depends on how you are applying. Digital applications (U.S. online renewal, DS-160, most visa portals) want the single photo file. Paper applications want prints, so use the 4 x 6 sheet — it holds six photos, and any shop that prints ordinary photos will print it for a few cents.
Should I use the background replacement?
Only if your authority permits it. It is a real help when no plain wall was available, but U.S. online passport renewal rejects digitally replaced backgrounds, and South Korea and Nigeria have similar bans; on those documents the feature is off by default and the page says so. When in doubt, photograph yourself against a real light-coloured wall from an arm's length away.
Will my photo definitely be accepted?
No tool can promise that, and this one does not. It gets the geometry right — the size, the head height and the resolution, which is where most mechanical refusals come from — and reports what it measured. Expression, recency, lighting evenness and glasses glare are still your judgement call; the rejection guide shows what each fault looks like.
