How to Convert Highlight Comments to Replace Text in Adobe Acrobat
Question details
The user wants to convert existing highlight comments into replace text annotations within a PDF document.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Reviewing and marking up a PDF where simple highlights need to be updated to explicit text replacement instructions.
- Observed behavior
- Adobe Acrobat does not provide a native, one-click feature to directly convert a highlight comment into a replace text annotation (which requires both a strikeout and a caret with new text).
Ensure you have the Comments pane open in Adobe Acrobat so you can easily locate, select, and modify your existing highlight annotations.
Manually Convert Highlights to Strikeout and Add a Caret Comment
Since a 'Replace Text' annotation is essentially a combination of a strikeout and an insert text (caret) comment, you can recreate this structure manually.
Adobe Acrobat treats 'Replace Text' as a dual-action comment. Converting a highlight directly isn't supported because the software doesn't know what the replacement text should be. You must manually change the highlight to a strikeout and insert the new text.
Open the Comments pane on the right side. Right-click the Highlight comment you want to change, select 'Properties', and change its appearance or markup type to 'StrikeOut'. Alternatively, delete the highlight and apply the Strikeout tool to the same text.
Select the 'Insert Text at Cursor' (caret) tool from the Comment toolbar. Click exactly at the end of the text you just struck out.
A text box will appear linked to the caret. Type the exact wording you want to replace the struck-out text with, then click 'Post' to save the comment.

Automate the Conversion using Acrobat JavaScript
For advanced users dealing with hundreds of comments, using a custom Acrobat JavaScript or a third-party plugin is the only way to automate the conversion.
Easily Annotate and Edit PDF Text with WPS Office
If complex annotation conversions in Acrobat are slowing down your workflow, try WPS Office. It provides an intuitive PDF commenting system and allows you to directly edit PDF text, eliminating the need for complicated 'Replace Text' markups.
- 1. Open your PDF in WPS Office: Launch WPS Office and open your PDF document to access the integrated PDF viewing and editing tools.
- 2. Use the Comment Tools: Navigate to the 'Comment' tab to easily apply highlights, strikeouts, or text insertions without navigating complex property menus.
- 3. Edit Text Directly: Instead of leaving replacement instructions for someone else, switch to the 'Edit' tab and click 'Edit Content' to directly replace the text in the PDF document.

Frequently Asked Questions
What exactly is a Replace Text comment in a PDF?
A Replace Text comment is a combined PDF annotation that consists of two parts: a strikeout line over the original text to signify deletion, and a caret (insert text) symbol immediately following it containing the new text to be added.
Why doesn't Acrobat have a one-click button to change Highlights to Replace Text?
Because a Highlight is a single-action markup indicating importance, whereas Replace Text is a dual-action instruction that requires user input for the new text. The software cannot automatically guess what the replacement text should be.
Can I export PDF comments to Word to make text replacement easier?
Yes. If the original document was created in Microsoft Word, you can export the PDF comments into the Word document. Word can then integrate these annotations as Track Changes, which often makes reviewing and replacing text much simpler.
