Passport Photo Maker

This tool does two jobs: it crops one photo to the exact pixel size of a chosen passport or ID photo at 300 DPI, and it lays whole copies of that crop out on a printable 4 × 6 inch sheet with a small gap between them. You position the picture yourself by dragging and zooming it inside a frame whose shape is the chosen size, so the head sits where you want it. Everything happens in your browser; the photo is never uploaded.

Being clear about what this is not. It is a cropping and sheet-layout tool. It does not detect, measure or align a face, and it does not automatically resize the head to a required share of the frame — nothing checks that the eyes are a certain distance from the bottom edge or that the head occupies a given share of the frame; you move and zoom the photo and judge it yourself. It does not remove, replace or change the background, and it does not clean up shadows, red eye, or lighting. And it does not verify the result against any government checklist: it cannot tell you whether your photo is acceptable, only that it is the right size and shape. The dashed oval and eye line drawn over the frame are a positioning guide, not a validation.

A passport photo has a physical size in millimetres, not a pixel size — the pixels depend on the resolution the print will use. This tool works at 300 DPI, the usual printing resolution for a photo like this, and converts each size with the exact factor 1 inch = 25.4 mm = 300 px. So a 35 × 45 mm photo becomes 413 × 531 px, and a 4 × 6 inch sheet becomes 1800 × 1200 px. The photo is cropped to fill the frame (the shorter side fits and the extra is trimmed), then zoomed, so the output is always exactly the size you chose and never stretched.

The sheet is a standard 4 × 6 inch photo print. The tool fits as many whole copies as will go — with about a 1 mm gap (12 px) between copies and the same margin from the edge, and the block of copies centred — and draws a hairline cut guide on each copy's edge, so the gaps double as cutting lines. How many fit depends on the size: a 35 × 45 mm photo fits 8 copies (4 across, 2 down) on a 4 × 6 in sheet at 300 DPI, while a 51 × 51 mm photo fits 2 (2 across, 1 down), because three 51 mm copies are wider than 6 inches. The count is shown under the preview before you generate anything.

How it works: your browser decodes the photo (a phone photo is turned upright using its EXIF orientation), draws the part of it inside the frame onto a canvas at the exact output pixel size, and encodes a JPEG. A second canvas, the 4 × 6 sheet, gets the same crop drawn at each position, then both are offered as downloads. Because the picture is redrawn on a canvas, EXIF metadata — camera, date and GPS location — is not copied into the result.

The limits that matter: this tool ships six nominal sizes, and the one you need may differ from what your authority currently publishes — the requirements across a single country, and between a printed application and an online one, are not uniform. Confirm the current rule with the authority handling your application (for example the US State Department for a US passport or visa, or GOV.UK for a UK passport), and check the printed result yourself before you send it. The saved JPEG carries no DPI metadata, so when you print the sheet, print it at 100% or 'actual size' — a printer or photo kiosk set to 'fit to page' will scale the copies and they will be the wrong physical size. Files are limited to 50 MB each and a canvas to about 100 megapixels (16,384 px per side); iPhones and iPads allow a smaller canvas (about 16.7 megapixels), and a very large photo may fail there with a message saying so.

1. Millimetres to pixels: px = round(mm ÷ 25.4 × DPI), with DPI fixed at 300. So 35 mm → 413 px and 45 mm → 531 px. 2. The single photo is widthPx × heightPx for the chosen size (for example 413 × 531 px for 35 × 45 mm). 3. The sheet is 152.4 × 101.6 mm (4 × 6 in) → 1800 × 1200 px at 300 DPI. 4. Copies per row = floor((sheetWidth − 2 × margin + gap) ÷ (photoWidth + gap)); per column the same with heights. n copies need n × photo + (n − 1) × gap pixels. The default gap and margin are 12 px each (about 1 mm at 300 DPI). If not even one copy fits in both directions, the count is 0 and no sheet is produced. 5. The block of copies is centred: startX = round((sheetWidth − usedWidth) ÷ 2), and each copy is at startX + column × (photoWidth + gap), startY + row × (photoHeight + gap). 6. The crop is a 'cover' fit: the photo is scaled so it covers the frame, the shorter side fitting exactly and the longer side overflowing, multiplied by the zoom (1× to 4×), then panned. The visible region is copied to the output canvas, halving in steps when it is reduced by more than 2× so it does not alias. 7. Both canvases are encoded to JPEG at the chosen quality (92 by default) and named passport-photo-<w>x<h>mm.jpg and passport-photo-sheet-4x6.jpg.
