What is the resolution of a PDF?

A 96dpi (dots per inch) resolution specifies that an inch in the PDF file is converted to 96 pixels in the output image. Likewise, 300dpi resolution means that an inch in the PDF file is converted to 300 pixels in the output image.

What is DPI in PDF?

PDF Image dpi. Most elements of a PDF file are device independent Vector graphics. This means that they will always appear 'smooth and clear'. By contrast images are bit-mapped. If the image is too small, it will be stretched and the pixels will become blocky.

How do you change the DPI on a PDF?

When you print, the first thing you see is the printing dialog. In the print dialog, you can select Printing Preferences. Click Advanced Options to get access to the DPI setting. A value of 300 DPI will usually result in a good quality output and a reasonable file size.

How do I change the DPI on a scanned document?

Scan. Just select your operating system. You should be able to change the DPI setting after selecting the format of how you are going to save the file and the Scan size. Click on the Advanced Settings link near the bottom and on the Scan tab, select the DPI there also.

How do you save a PDF, so it can't be edited?

Click the “OK” button. Click the “File” menu and choose “Save” or “Save As” to save the encrypted document. Now, no one can edit the document without first entering the password you entered.
