Crop a passport or ID photo

A passport photo is a portrait at exact dimensions — pick the document size, frame the crop, export at print resolution.

The job

Passport photos come in exact millimeter sizes — 51×51 for US, 35×45 for Japan/EU/UK. Cropping to the right aspect and printing at the right DPI is the mechanical half of the job.

Crop

Choose a photo, pick the preset, set DPI, and adjust zoom and position on the live preview. The export is a PNG at the exact pixel dimensions that size×DPI implies.

300 DPI is the standard print density; labs that accept files also accept 600.
Position the face so the eyes sit in the upper half — most specs want the head 70–80% of the frame.

Worked example

Japan passport: 35×45 mm at 300 DPI → 413×531 px. A phone portrait crops to that with a little headroom above the eyes.

Where it stops

The tool cuts and scales only — it cannot certify the photo meets an authority's rules (plain background, neutral expression, recent, head-size ratio). Check the issuing body's checklist before printing.
