How to Undo a PDF File

By Andrew Meer

Applications such as Adobe Acrobat and Adobe Reader feature a built-in option that allows you to automatically undo any unnecessary changes you made to a PDF (Portable Document Format) file while editing it. This feature, titled "Undo," can save you a lot of time since you do not need to undo the changes yourself.

Step 1

Click "Edit" on the Adobe Acrobat or Adobe Reader window to open up a drop-down menu.

Step 2

Point your mouse to the option labeled "Undo."

Step 3

Click the option labeled "Undo" to restore the last change you did to the PDF file. You must repeatedly click "Undo" if you want to restore any more changes.

Tips & Warnings

  • Alternatively, you can also press the "Ctrl" and the "Z" keys together to undo any changes made to a PDF file when using Adobe Acrobat or Adobe Reader.
