Image DPI / PPI Checker

What is DPI and why does it matter?

DPI (dots per inch) or PPI (pixels per inch) tells printers how large an image should be printed. Print shops usually ask for 300 DPI. The same 3000-pixel image prints about 25 cm wide at 300 DPI and about 105 cm wide at 72 DPI.

What the checker shows

It reads the JFIF, EXIF, PNG pHYs and BMP headers directly and shows the stored DPI value. If the file has no DPI information it says so clearly and never invents a value. It also calculates the print size in centimetres and inches at 300, 150 and 72 DPI based on the pixel dimensions.

Private and quick

Your file is read in the browser, so you can check it in seconds before sending it to print.
