How to Resize an Image in Centimeters (cm)
Most online forms, passport applications, and print services specify photo requirements in centimeters rather than pixels. Our centimeter resizer automatically converts your desired physical dimensions into crisp pixel values based on your target print resolution (defaults to standard 300 DPI).
Upload Your Photo
Select or drag your JPG, PNG, or WebP photo into the workspace.
Enter Width and Height in cm
Type your target centimeters (e.g. 3.5 × 4.5 cm). Toggle aspect ratio lock and select your print DPI.

Centimeters to Pixels Formula (At 300 DPI)
The mathematical formula used to calculate pixel dimensions from centimeters is: Pixels = (Size in cm / 2.54) × DPI.
At standard 300 DPI print resolution, 1 centimeter equals approximately 118.11 pixels. For example, a 3.5 × 4.5 cm passport photo calculates to 413 × 531 pixels.
