Pixel conversion depends on the selected DPI. Changing DPI changes the calculated pixel dimensions; it does not change the physical size.

IMPORTANT

Conversion is not compliance

A 35 × 45 mm image, for example, can still have different head-size, background, pixel, file-size or submission-channel requirements depending on the document. Use FastIDPhoto's requirements database to check the complete rule before creating the final photo.
