Free Image Scaler
Passport and ID photo requirements vary by country, and a rejected photo means starting the application again. This page covers the common sizes and how to crop an existing photo to the right proportions.
The United States uses 2 x 2 inches (51 x 51 mm), a 1:1 square. Most of Europe, the UK, Australia and India use 35 x 45 mm, which is a 7:9 ratio. Canada uses 50 x 70 mm. China uses 33 x 48 mm. Always confirm against your own government’s current guidance before submitting, because these change and some countries have additional rules for infants or religious head coverings.
A cropper works in proportions, not millimetres - so what you are matching is the ratio: 1:1 for a US photo, roughly 7:9 for a 35 x 45 mm photo. Once the proportion is right, the physical size is set when you print or when the upload form resizes it. If the application also specifies a minimum pixel size, check your cropped result meets it before submitting.
Most countries specify how much of the frame the head must occupy, typically somewhere between 70% and 80% of the height from chin to crown, with the eyes in a defined band. A photo cropped to exactly the right ratio can still be rejected if the head is too large, too small, or off-centre, so check your country’s head-height rule as well as the dimensions.
Yes, as long as the original has enough resolution and meets the background and expression rules. Cropping sets the proportions; it cannot fix a busy background or poor lighting.
Approximately 7:9. Set a custom ratio of 35:45 in the cropper and the proportions will match.
No. Cropping happens entirely in your browser, which matters more than usual for an identity document.
