Photo Size Converter — MM, Inch and Pixel
Enter a photo size in millimetres, inches or pixels and convert it to the other two. Then pick a country preset and resize your photo to that spec directly in the browser.
Sign in to generate. A headshot and an ID photo each use one credit.
Background35×45 mm, 413×531. Head proportion follows this size. Clothes, glasses, and expression stay.The whole head needs to show, with a little space around it. A head cut at the top, sides, or chin is not generated, and the credit is returned.
The headshot keeps the same face and sends the photo to an image service. An ID photo is cropped in your browser and the original is not uploaded. Neither result is stored—download it yourself.

Convert, then crop
- Use Custom size for any millimetre pair, or open a country preset page.
