Photo Resizer

Resize a photo to the exact size your form asks for — in pixels, or in millimetres at a chosen DPI.

1. Upload a photo

2. Choose a size preset

Lock aspect ratio (changing width updates height from the original photo)

Millimetres: pixels = mm ÷ 25.4 × DPI. For example, 35 × 45 mm at 300 DPI is 413 × 531 px.
