How to Change the DPI of a PDF

 

Changing the DPI (dots per inch) of a PDF can improve its quality for printing or screen display. Here’s a step-by-step method using Adobe Acrobat:

1. Open PDF: Open the PDF in Adobe Acrobat.
2. Export: Go to “File” > “Export To” > “Image” > “JPEG” or another image format.
3. Set DPI: In the “Settings” menu, adjust the DPI (e.g., 300 DPI for high quality).
4. Save: Export the images.
5. Recreate PDF: Use Adobe Acrobat or another tool to convert the images back to a PDF.

If you’re looking for online tools, Adobe Acrobat is generally recommended for changing DPI. However, if you need to handle other PDF management tasks, such as extracting text from scanned documents or converting formats, pdftopdf.ai is an excellent option.
