The practical guide
Prepare exact passport or visa photo dimensions—and know what the tool cannot validate.
The tool provides clearly labeled size references for common U.S., UK printed, 35×45 mm, and Canada printed workflows. Official rules can also govern head size, pose, expression, lighting, recency, background, editing, and file delivery.
01Start with the correct application type
A country may use different rules for printed photos, digital uploads, passports, visas, renewals, and overseas applications. Select a size only after checking the current authority page linked beside the preset.
02Position the portrait in an exact-ratio preview
The preview uses the selected output aspect ratio. Zoom and horizontal or vertical controls change the same crop used for the downloaded pixel dimensions.
03Choose pixels, physical units, and DPI deliberately
Inches and millimetres are converted to pixels using the selected DPI. For example, a 2 × 2 inch photo at 300 DPI produces a 600 × 600 pixel file.
04Use file-size targeting only when required
JPG file size depends on image detail and compression. Exact dimensions take priority, and the result reports when a requested KB ceiling cannot be reached without excessive quality loss.
05Print sheets include measurable output
The 4 × 6 inch and A4 options tile as many exact-size copies as fit at the chosen DPI, add cut guides, and report the final copy count and sheet dimensions.
06Background changes need extra caution
The optional segmentation model loads only when requested and runs locally. Inspect hair and clothing edges, and do not use digital background alteration when the relevant authority prohibits edited photos.
