Image resizer in cm: what to know

Choose centimetres in the unit box and type the size you need, for example 3.5 × 4.5 cm. The tool converts it to pixels at 300 DPI, so a 3.5 × 4.5 cm picture is about 413 × 531 px.

The cm size matters when you print the picture or when a form states a physical size. For uploads, check whether the form wants pixels or KB as well.

Tips

300 DPI is a good choice for printing.
Switch to inches if you prefer.
Crop to the right shape before resizing.
