To change the DPI (dots per inch) of a PDF, you typically need to use a PDF editing software or a conversion tool. First, open the PDF in the software, then look for options to export or save the file as an image or a new PDF, where you can specify the desired DPI settings. Alternatively, some tools allow you to directly adjust the resolution settings when printing the PDF. Always remember to save a copy of the original file before making changes.
I think what you mean is to change the resolution of the PDF files? 'Cause I found this : "e.g. a 300 dpi printer has "pixels" that are 1/300 inches in size, while a 72dpi monitor has 1/72 inch sized pixels. A 100x100@72dpi image on a monitor would have to be printed out at about 417x417 printer pixels to have the same apparent size (300/72 = 4.16666)" So if it does, here is the solution: In Adobe Acrobat, "Edit > Preferences > Convert to PDF", choose the file you want to change, select "Adobe PDF Settings > Editing > Standard" and then Edit again to change the resolution. May this will do some help.
To check the DPI (dots per inch) of a PDF file in Adobe Acrobat, open the file and go to "File" > "Properties." In the "Document Properties" window, navigate to the "Fonts" tab to see the resolution of images used in the document. Alternatively, you can use the "Preflight" tool (found under "View" > "Tools" > "Print Production") to analyze the PDF and get detailed information about image resolutions, including DPI.

Dot Per Inch (DPI)
DPI stands for Dots Per Inch.....
A high resolution DPI for images is typically considered to be 300 DPI or higher.
1200 dpi because dpi stands for dot per inch, there for 1200 dpi gives 1200 dots per inch instead of 600 dpi only giving 600 dots per inch thus 1200 dpi gives a better resolution
