Question details
The user wants to configure Adobe Acrobat or Reader to open PDF documents with the Tools pane collapsed by default.

- Product
- Adobe Acrobat / Reader
- Device & OS
- not provided
- Scenario
- Opening PDF documents for viewing or editing without the distraction of the right-hand Tools pane taking up screen space.
- Observed behavior
- The Tools pane automatically expands every time a new PDF document is opened, requiring the user to manually close it each time.
Ensure your Adobe Acrobat or Reader is updated to the latest version, as the location of preference settings can vary slightly in older software releases.
Disable the 'Open Tools pane' Preference
Adjusting the built-in Preferences menu is the most effective way to permanently keep the Tools pane closed upon launching any PDF.
This built-in setting tells Acrobat to stop forcing the Tools pane open for every document. Once applied, your PDFs will open with a cleaner, wider viewing area.
Open Adobe Acrobat or Reader and collapse the right-hand Tools pane manually by clicking the small arrow or hide button on the sidebar.
Navigate to the top menu bar, click on 'Edit', and select 'Preferences' from the dropdown list. You can also use the keyboard shortcut Ctrl+K (Windows) or Cmd+K (Mac).
In the Preferences dialog box, look at the left-hand sidebar under the 'Categories' list and click on 'Documents'.
Under the 'Open Settings' section on the right, find and clear the checkbox labeled 'Open Tools pane for each document'.
Click the 'OK' button at the bottom of the window to apply the changes, then restart Adobe Acrobat or Reader to ensure your PDFs open with the new layout.

Frequently Asked Questions
Why does the Tools pane keep opening even after I changed the setting?
If the pane keeps opening, you might not have restarted Adobe Acrobat after changing the preference, or your organization's IT policy may be overriding user settings. Make sure to restart the application completely after clicking OK.
Can I hide the Tools pane in older versions of Adobe Reader?
Yes, but the exact setting location might differ. In older versions like Reader XI, you can typically go to Edit > Preferences > Documents and look for the 'Remember current state of Tools Pane' option instead.
Is there a keyboard shortcut to quickly toggle the Tools pane?
Yes, you can usually press Shift + F4 on Windows or Mac to quickly toggle the visibility of the right-hand Tools pane in Adobe Acrobat without needing to click through menus.
Does this setting apply to all PDF files I open?
Yes, once you uncheck 'Open Tools pane for each document' in your preferences, Adobe will apply this default layout rule globally to all future PDFs you open on that specific computer.
