9 Best Free DPI Checker Software For Windows

This article lists the Best Free DPI Checker Software For Windows. Using any of these software, you can view the “Dots Per Inch” i.e. DPI of an image.

Many times, users get confused between DPI and PPI (pixels per inch) of pictures. Both the terms are similar, but they are not same. While PPI is meant for display resolution of an image, DPI is strictly used in terms of printing resolution. So, to check DPI of a picture, you can use any of these free DPI checker software.

You can check DPI of an image using Windows File Explorer too. You just need to right-click on the image and go to Properties > Details tab. There, you can view DPI of an image along with other information like height, width, size, creation date, etc. For a software alternative, you can go through this list to find one. Most of these software let you customize the DPI of an image too. Hence, using a software to check and change the value of DPI is more desirable. As these software are primarily editing tools, you can enhance your images too.
