Change Image DPI to 300, 150, 72 or any value
Choose a JPG or PNG, pick the DPI your form or printer asks for, and download. Pixels and quality stay exactly the same.
DPI Changer
Change the embedded print-density setting without resizing or recompressing your image. Pixel dimensions, image detail and PNG transparency stay the same. File size may change slightly because metadata changes.
A higher DPI number does not sharpen a blurry photo or add pixels. Some apps ignore embedded DPI; print quality also depends on pixel dimensions and the chosen print size.
Have a WebP or HEIC photo? Convert it to JPG or PNG first using our converters. WebP → JPG/PNG · HEIC → JPG/PNG

Frequently asked questions
How do I change an image to 300 DPI?
Choose the JPG or PNG, pick 300 (or type any value from 1 to 2,400), press Change DPI and download. The file keeps its original format.
Does 300 DPI make my photo sharper?
No. DPI only tells printers how big to print the pixels. It does not add detail; for a sharp print you need enough pixels for the size you want.
My image is WebP or HEIC. Can I change its DPI?
Convert it to JPG first with WebP to JPG or HEIC to JPG, then change the DPI here.
Is my image uploaded?
No. The DPI is changed inside your browser, so the image stays on your device.
