PDF resolution refers to the number of pixels per inch (PPI) in a PDF document. A higher PPI results in a sharper, more detailed image, while a lower PPI can make the image appear blurry or pixelated. Checking the resolution of a PDF is important for ensuring that the image will be clear and readable when printed or viewed on a screen.
There are several ways to check the resolution of a PDF. One way is to open the PDF in a PDF viewer, such as Adobe Acrobat Reader, and then go to the “File” menu and select “Properties.” The “Properties” dialog box will display the resolution of the PDF in the “General” tab.
