Resize a photo in cm, pixels or inches

Choose a photo and type the size in pixels, cm, mm or inches: it is cropped to fit, never stretched.

What this tool does

Forms ask for a photo in pixels ("600 × 600"), in centimetres or millimetres ("3.5 × 4.5 cm") or in inches ("2 × 2"). This tool works between them, fits the picture without stretching it, and saves the print quality (DPI) in the file. You can add a KB limit as well, so one photo meets both rules. Or keep every pixel and change only the DPI saved in the file.

How it works

  1. Choose the photo.
  2. Pick a common size or type the width and height in pixels, millimetres, centimetres or inches.
  3. Drag the picture to frame it, then download. The DPI is saved in the file, so it prints at the right size.

Questions and answers

Will it stretch my photo?

No. You choose which part of the photo fills the new shape, so faces never get squashed.

How do I resize a photo in cm and KB at the same time?

Choose "My own size", pick cm as the unit and type the width and height. Then open "More options" and fill in "Also keep the file under (KB)". The result page checks both.

What DPI should I use?

300 DPI is the standard for printed photos. For a photo that is only uploaded, the pixel size is what matters.

How do I change the DPI without changing the pixels?

Choose "Change only the DPI", type the DPI you need, such as 300, and press "Next". You get the same photo with the new DPI saved in it, and every pixel stays as it was. It works on JPG and PNG files.

Is my photo uploaded?

No. Everything happens in your browser.
