4 x 4 cm Photo Maker
The 4 x 4 cm (40 x 40 mm) format is used by the documents listed below — each with its own head-height rule, so check yours before you crop. This page covers the format itself: exact sizes in millimetres, centimetres, inches and pixels, how many fit on a print sheet, and a free cropper with head-position guides. Everything runs locally in your browser: no ads, no watermark, and your photo is never uploaded.

Frequently asked questions
How many pixels is a 4 x 4 cm photo?
472 x 472 px at 300 DPI, or 945 x 945 px at 600 DPI for high-quality printing. In inches that is 1.57 x 1.57 in; in millimeters 40 x 40 mm.
How do I resize a picture to 4 x 4 cm?
Open the free maker with this size preselected, upload any portrait, drag and zoom until the head sits between the guides, and download the exactly-sized JPG. No signup, no ads, no watermark — and your photo is processed entirely in your browser.
How do I print 4 x 4 cm photos?
Download the 4 x 6 in sheet — the maker packs as many 4 x 4 cm photos as fit and adds cut lines — then print it as a regular borderless 4x6 photo at 100% scale at any photo shop, pharmacy photo kiosk or at home.
Which documents use 4 x 4 cm photos?
Argentina DNI Photo.
Do all 4 x 4 cm photos have the same head height?
No. 4 x 4 cm is only the outer size of the print. Across the documents that use it, the required head height ranges from 25 mm to 31 mm from chin to crown, so a photo accepted for one may be rejected for another. Open the specific document above and use its preset.
