How the Chinese ID & passport photo process works
China's most common formats are the 33×48 mm passport/visa photo and the domestic 一寸 (25×35 mm) and 二寸 (35×49 mm) ID sizes. Passport and visa photos use a plain white background, while many domestic uses (resumes, school, social-security cards) allow white, blue, or red. Digital submissions often have strict pixel and file-size rules — for example 354×472 px for the passport photo, kept within a kilobyte cap. Snapfora outputs the exact pixel size, lets you switch the background colour, and compresses to the file limit so the online system accepts the upload on the first try.
