No. GetResize processes your files inside your own browser. They never leave your device, so the tool is private and works fast even on slow connections.

What DPI should I use?

300 DPI is the standard for photo prints and documents. 150 DPI is fine for large posters viewed from a distance. Screens ignore DPI and only care about pixels.

How many pixels is 1 cm?

At 300 DPI, 1 cm is about 118 pixels. At 96 DPI (the usual screen value) it is about 38 pixels.

About Resize Image in CM

Printers, photo labs and application forms often ask for images in centimeters or inches rather than pixels. Pixels = size in inches × DPI, so a 10 × 15 cm photo at 300 DPI is 1181 × 1772 pixels. GetResize does the math and writes the DPI into the JPG or PNG so it prints at the right size.

If your photo has a different shape than the size you need, it is cropped from the center by default. You can also fit it with borders instead.
