Type the size in centimetres, choose the DPI (300 for print), and download a photo that prints at exactly that size.
🔒 Shape kept — type one side, the other follows each photo. Unlock to set both.
This image resizer changes the width and height of your photos to any size you need — in pixels, inches, centimetres, millimetres or percent.
When the new shape is different from your photo, you choose what happens: crop to fill (nothing stretched), fit the whole picture with a background colour, or stretch.
pixels = inches × DPI = (cm ÷ 2.54) × DPI = (mm ÷ 25.4) × DPI
Inches, cm and mm are turned into pixels using the DPI (dots per inch): pixels = inches × DPI. At 300 DPI, 1 inch = 300 px and 35 mm ≈ 413 px.
The DPI is saved inside JPG and PNG files, so the photo prints at the right physical size.
If you set a KB limit, the quality is lowered step by step until the file fits, and the size is reduced only if that is not enough.
