Can Adobe Acrobat Compare PDF Edits with Annotations?
Question details
The user needs to compare an original PDF containing comments with a revised PDF to determine if any requested edits or annotations were missed during the revision process.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Reviewing document revisions based on multiple comments and annotations left by collaborators.
- Observed behavior
- Acrobat does not provide a reliable, automatic process for matching every annotation to a completed text change because text edits often shift the layout of the entire document.
Before attempting to verify document revisions, ensure you have both the original annotated PDF and the newly revised PDF saved in an easily accessible folder.
Manually Track and Review PDF Annotations
Since Acrobat cannot automatically map specific text changes to past comments due to layout shifts, a structured manual review process is the most reliable method.
Developing an automated process for matching comments to text edits is highly complicated. Even a minor text change can shift paragraphs or alter the layout of the entire document, which displaces the original anchor points of the annotations. Therefore, automated comparison tools cannot reliably verify if an edit perfectly satisfies a specific comment.
Open both the original annotated PDF and the revised PDF in your PDF viewer, arranging the windows side-by-side for easy visual comparison.
In the original document, open the 'Comments' pane (usually located on the right toolbar) to view the complete list of requested edits in chronological order.
Click on each comment in the list to navigate to the exact location in the original file, then look at the corresponding section in the revised file to verify the text was updated.
Right-click the verified comment and select 'Resolve' or add a checkmark. Repeat this process until all annotations have been reviewed.

Easily Manage PDF Comments and Revisions with WPS Office
While automated annotation matching is difficult across all software, WPS Office provides an intuitive PDF editor that makes side-by-side comparison and comprehensive comment tracking incredibly simple.
- 1. Open Your PDFs: Launch WPS Office and open both the original annotated PDF and your newly revised PDF file.
- 2. Enable Side-by-Side View: Go to the 'View' tab and select 'View Side by Side' to arrange both documents on your screen simultaneously.
- 3. Access Annotations: Click on the 'Comment' tab in the original document to open the full list of annotations in the right-hand panel.
- 4. Review and Resolve: Click through the comment list to verify changes in the revised document, marking each comment as resolved once confirmed.

Frequently Asked Questions
Why can't PDF editors automatically check if my comments were addressed?
When text is added or removed, the document layout often shifts. This displacement unlinks the original anchor points of the annotations from the new text, making it technically difficult for software to reliably verify if a new edit matches an old comment.
Does the 'Compare Files' feature in Acrobat show missed comments?
No. The 'Compare Files' tool strictly highlights visual and text differences between two documents. It does not cross-reference those text differences with unresolved user comments or sticky notes.
How can I make tracking PDF edits easier for my team?
Establish a clear review process. Request that editors reply to specific comments with 'Done' or use the 'Resolve' feature in the PDF viewer immediately after they complete an edit. This establishes a clear review trail inside the document itself.
