Reset the Toolbar via the Right-Click Menu
This is the quickest way to restore the default toolbar layout if temporary UI glitches hide your PDF annotation tools.
Often, toolbars can become unintentionally customized or hidden due to workspace changes. Using the built-in reset function will revert the Comments toolbar back to its factory default state, bringing back all standard tools like the Sticky Note and Highlighter.
Locate an empty space on your Acrobat Reader DC toolbar or right directly over the existing limited Comments toolbar.
From the context menu that appears, click on 'Reset Toolbars'. This action will instantly reload the default tools layout.

Repair or Reinstall Acrobat Reader DC
If resetting the toolbar doesn't work, repairing or reinstalling the software can fix corrupted configuration files causing the UI error.
Use WPS PDF to Effortlessly Comment and Annotate
Avoid missing toolbar glitches by using WPS PDF to read, edit, and annotate your PDF documents. WPS Office provides a highly stable, user-friendly interface with all essential comment tools readily available by default.
- 1. Download WPS Office: Install WPS Office for free from the official website.
- 2. Open your PDF: Launch WPS PDF and open the document you wish to review.
- 3. Access the Comment tab: Navigate to the 'Comment' tab on the top ribbon menu to view the full array of annotation options.
- 4. Start Annotating: Select the 'Highlight' or 'Note' tools to start marking up your document effortlessly.

Frequently Asked Questions
Why did my Comments toolbar disappear in Adobe Acrobat?
Toolbars can sometimes become hidden or customized accidentally. This often happens after an automatic software update, or if the PDF workspace layout was inadvertently modified by dragging tools off the panel.
Can I customize the tools on my PDF Comments toolbar?
Yes, in most PDF readers like Adobe Acrobat and WPS PDF, you can right-click the toolbar and select 'Customize' to add or remove specific annotation tools to fit your specific workflow.
Are my existing PDF comments lost if I reinstall the software?
No. Comments, highlights, and annotations are saved directly within the PDF file itself, not the software application. As long as you previously saved the document, your sticky notes will remain intact and visible when you reinstall the software or use another PDF reader.
