Enter values as noted below and then click OK. Open an image in any bitmap format, like JPEG, PNG, or TIFF. Enter your desired DPI - Dots Per Inch (Today the term is often misused, usually means PPI, which stands for Pixels Per Inch).

This can be verified using metadata tools such as ExifTool. The official PNG specification states that the PNG resolution unit is in metres (not inches). The DPI of a digital image is calculated by dividing the total number of dots wide by the total number of inches wide OR by calculating the total number of dots high by the total number of inches high. Go to the “Details” tab to see the image’s dimensions and resolution. Right-click on the image and then select “Properties.” A window will appear with the image’s details. You’ll see the DPI in the Image section, labeled Horizontal Resolution and Vertical Resolution. To find out an image’s DPI in Windows, right-click on the file name and select Properties > Details.

How do I tell the Resolution in DPI of each image in my layout When I go to print to PDF I see that 'Image Resolution below 96 DPI' as an 'Issue' I tried clicking each graphic image and looking at properties but didn't see the Resolution. You can see the DPI of the image by using, for example, GIMP by using image -> image properties. have a 1x1' image with a resolution of 600dpi, but when you place this in the PDF file at a size of 4x4', you get a resulting resolution of 150dpi. In the PNG file two 4-byte numbers gives the pixels per meter og the width and height, which can be converted to DPI by multiplying with 0.0254 meters/inch. The problem is that even if you extract all image files, it will not give you an effective resolution - it all depends on how big the image is when it's placed on the PDF page.
