Resize an image in centimeters
Enter the width and height you need in cm and pick a resolution. The tool converts the size to pixels for you, so the image prints or uploads at the right physical size.
Pixels = centimeters ÷ 2.54 × DPI. At 300 DPI, 1 cm is about 118 pixels, so a 3.5 × 4.5 cm photo is roughly 413 × 531 pixels.

Frequently asked questions
How are centimeters converted to pixels?
Pixels equal centimeters divided by 2.54, multiplied by the DPI. A higher DPI gives more pixels for the same physical size.
Which DPI should I choose?
Use 300 DPI for printing, and 72 or 150 DPI for screens and most online forms.
What happens if I turn off Keep aspect ratio?
The image is stretched to the exact width and height you enter, which can distort it.
