Passport photo size and crop
Sizes in millimetres or inches are converted to exact pixels at the DPI you choose. The photo must still meet the rules of the authority that issues your document.
SnapCut crops and sizes the photo only. It does not check your face, expression or background.
Your photo never leaves this device. To check, open your browser's developer tools, choose Network, and crop a photo: no request carries it.
This page opens on 35 x 45 mm at 300 dpi, a size many countries use, which is 413 x 531 pixels. SnapCut converts a size in millimetres, centimetres or inches to whole pixels from the DPI, and shows the result under the fields so you can see exactly what the file will be.
The Passport and ID list holds several sizes: United Kingdom printed and digital, a Schengen visa under Czech rules, Canada print and digital, a China visa, and two for Bangladesh. Each one that comes from an authority links to the page where that authority sets the size, and the UK and Canada digital sizes warn when the file is outside the allowed size.
SnapCut crops and sizes the photo only. The photo must still meet the rules of the authority that issues your document, including the head position, the background, the expression and the age of the picture. Read those rules before you apply, because an office can refuse a photo that is the right size but breaks them.
Nothing leaves your device: a passport photo is personal data, so the crop is made in your browser and no file is sent anywhere. The download is a JPEG or a PNG. A size in millimetres, centimetres or inches records its DPI in the file, so a print shop reads the correct size; a size in pixels, including the UK and Canada digital sizes, records none.
