Frequently Asked Questions

Why are the bottoms of my PDF dialog boxes cut off?

Dialog boxes often get cut off when your system's display scaling is set too high (such as 150% or more) or your screen resolution is too low. Adjusting your Windows display scale to 100% or 125% usually brings the hidden buttons back into view.

Is there a keyboard shortcut to trigger the missing 'Add' or 'OK' button?

Yes. If a dialog box is cut off and you cannot see the 'OK', 'Add', or 'Submit' button, you can often press the 'Enter' key on your keyboard to trigger the default primary action. To close the dialog without saving, press the 'Esc' key.

Does reinstalling Adobe Acrobat delete my PDF files?

No, uninstalling and reinstalling the application only removes the software program files from your system. Your personal PDF documents, folders, and saved data remain completely safe on your hard drive.

How do I add custom PDF page sizes without using Acrobat?

You can use alternative PDF editors like WPS Office, or set custom page sizes directly through your system's virtual printer settings. Navigate to 'Devices and Printers', select your 'Print to PDF' driver properties, and define a custom paper size there.
