🪪 Passport Photo Maker
Crop to 35×45 mm, 2×2 in or any size at a chosen DPI, with head-height guides, then lay copies onto a 4×6 or A4 sheet with cut lines.

What Passport Photo Maker Does
An ID photo has two kinds of requirement, and only one of them can be checked by a web page. The geometry is objective: a physical size in millimetres, a resolution, and a head that occupies a stated proportion of the frame. The rest — expression, glasses, headwear, shadow on the background, whether the lighting is even — is a judgement about the content of the picture, it differs between countries, and it changes. Several tools on this search advertise compliance for dozens of countries. This one does not, because a specification table that goes stale gets applications rejected, and none of those figures could be verified against an official source.
So this does the geometry exactly. You give the size in millimetres and the DPI, and the crop is computed in the source image’s own pixels so the output is precise at whatever resolution you asked for — with that resolution written into the saved JPG, which matters for portals that inspect the embedded value rather than the pixel dimensions.
The head-height guide takes its numbers from you rather than assuming them. Requirements are typically phrased as "the head must occupy between X and Y percent of the frame height", with the eyes at a given position, and those figures are on the form in front of you. The overlay draws that band and an eye line so you can see where the crop has to land instead of guessing.
The part that actually finishes the job is the print sheet, and it is the part most free tools leave out. One photo is a file; what you usually need is six of them at the correct physical size on a piece of photo paper, with lines to cut along.
How to Use Passport Photo Maker
- Add a portrait, or drop it onto the box
- Choose the photo size in millimetres and the DPI your form asks for
- Set the head-height percentage from your form, then zoom and move until the face sits inside the guides
- Save the single photo, and the print sheet if you need physical copies
Formula Used by Passport Photo Maker
Millimetres to pixels, and how many fit on a sheet
px = mm ÷ 25.4 × dpi; columns = ⌊(sheetPx − 2·margin + gap) ÷ (photoPx + gap)⌋
- 25.4
- millimetres in an inch, exact by the 1959 international definition
- gap
- the space left between photos so there is something to cut along
Worked example
35 × 45 mm photos at 300 DPI on 4 × 6 inch paper, 3 mm gaps and a 4 mm margin.
- Photo: 35 ÷ 25.4 × 300 = 413 px wide, 45 ÷ 25.4 × 300 = 531 px tall
- Sheet: 152.4 mm → 1800 px wide, 101.6 mm → 1200 px tall
- Across: (1800 − 94 + 35) ÷ (413 + 35) = 3.88 → 3 columns
- Down: (1200 − 94 + 35) ÷ (531 + 35) = 2.01 → 2 rows
Result: Six photos on one 4 × 6 print — the standard sheet a photo shop would hand you.
Common ID photo sizes in pixels
The geometry only. Always use the size your own form specifies — these are the sizes that recur, not a standard.
| Physical size | At 300 DPI | At 600 DPI |
|---|---|---|
| 35 × 45 mm | 413 × 531 | 827 × 1063 |
| 2 × 2 in (50.8 × 50.8 mm) | 600 × 600 | 1200 × 1200 |
| 50 × 70 mm | 591 × 827 | 1181 × 1654 |
| 33 × 48 mm | 390 × 567 | 780 × 1134 |
| 25 × 35 mm | 295 × 413 | 591 × 827 |
How many fit on a sheet at 300 DPI
With a 3 mm gap and a 4 mm margin, as the tool lays them out.
| Photo | 4 × 6 in | 5 × 7 in | A4 |
|---|---|---|---|
| 35 × 45 mm | 6 (3 × 2) | 8 (4 × 2) | 30 (5 × 6) |
| 2 × 2 in | 2 (2 × 1) | 6 (3 × 2) | 15 (3 × 5) |
| 25 × 35 mm | 10 (5 × 2) | 18 (6 × 3) | 49 (7 × 7) |
How to Read Your Result
Print at 100%, never "fit to page"
This is the most common way a home-printed set fails. "Fit to page" and "scale to fit" rescale the sheet, so every photo on it comes out the wrong physical size — and an ID photo that is two millimetres wrong is rejected. Choose actual size, and measure one photo with a ruler before cutting the rest.
Do the background first
A plain, evenly lit background is a near-universal requirement and the hardest to get right at home. Remove the background and set it to white or light blue before sizing, rather than trying to crop around a busy room.
The guides are yours to set
The head-height band defaults to a common figure but the number that matters is on your form. Set it there first, then zoom and reposition until the head sits inside the band with the eyes near the line — in that order, because changing the band after framing means doing the framing again.
Limitations & Accuracy Notes
- No compliance checking of any kind. Expression, glasses, headwear, shadows and background are not assessed, and no country’s rules are encoded here.
- No face detection — you position the photo yourself against the guides.
- No background replacement; use the background remover first if you need a plain ground.
- The eye line is drawn at a typical position within the head band as a visual aid, not as a specification.
- Printing accuracy depends on your printer and its settings; the file is correct at the DPI you set, and "fit to page" will still ruin it.
