Change image DPI to 72, 150, 300 or 600 without quality loss.

Your files are processed on your device and are never uploaded.

Change the DPI of an image to 72, 96, 150, 200, 300, 600 or any custom value. Many government, exam and printing portals reject photos that are not "300 DPI" – this tool fixes that in one click without touching the picture itself.

Convert DPI with ShrinkBee

Only the DPI value stored inside the file changes. The pixels, dimensions and quality stay exactly the same, so your photo looks identical while meeting the requirement.

How to Convert Image DPI

  1. Choose your image: JPG or PNG work best.
  2. Pick the new DPI: 72, 96, 150, 200, 300 or 600 – or enter a custom DPI.
  3. Click Change DPI and download the updated image.

What Is DPI?

DPI (dots per inch) tells printers how many pixels to place in each inch of paper. A photo 600 pixels wide prints 2 inches wide at 300 DPI, or about 8.3 inches wide at 72 DPI. Screens ignore DPI, so changing it does not affect how the photo looks on a computer or phone.

Which DPI Should I Use?

  • 300 DPI – the standard for printing and for most official forms that state a DPI.
  • 200 DPI – common for scanned documents and signatures.
  • 600 DPI – high-detail printing and archival scans.
  • 72 / 96 DPI – web and screen images.

Need the photo to print at a specific physical size as well? Use Resize Image in Centimeters, which sets both the size and the DPI.
