My country uses a different pixel size or PPI

If your form lists exact pixels, enter those in the checker instead of relying on the 300 PPI (413 × 531 px) estimate.

Is this right for a UK or Canadian passport?

Not necessarily. UK and Canadian digital passport photos have their own rules and must be unaltered — see our UK and Canada passport pages before using a cropped/compressed file.

Task

Make a 35×45 mm photo under 100 KB

35 × 45 mm is a physical print size used by several countries' passport and visa photos. It is not a single global standard: the exact pixel size, file format, and file-size rules differ by country, document type, and portal, so always confirm the official spec before you export.

At 300 PPI, 35 × 45 mm works out to 413 × 531 pixels, and this page prepares that size. The 100 KB cap here is only an example to keep the file small — it is not an official requirement. Enter whatever pixel size and file-size limit your form actually lists.

Maximum file size: 100 KB
