How to Combine PDF Comments and Annotations into One File
Product
PDF Editor
Device & OS
not provided
Scenario
Reviewing multiple PDF documents with individual feedback and annotations that need to be centralized for final processing.
Observed behavior
Annotations are currently isolated within separate PDF files, making it difficult to review all feedback comprehensively in one place.
Before you start

Ensure that the source PDFs and the destination PDF share the exact same layout and page count, as imported comments rely on specific page coordinates to align correctly.

Solution 1Recommended

Export and Import Comments Data

Use the built-in Comments List panel to export annotations as a data file from individual PDFs and import them into a single master PDF.

This method extracts only the annotation data (such as highlights, text boxes, and sticky notes) without merging the actual PDF pages. This keeps your document clean while aggregating all feedback.

1
Open the source PDF

Open the first PDF containing the annotations you wish to extract and navigate to the Comments List panel, usually located on the left or right sidebar.

2
Export annotations

Click the Options menu within the Comments List panel and select 'Export All to Data File'. Choose a location on your computer to save the comments data file (.fdf or .xfdf).

3
Open destination PDF

Open the master or destination PDF file where you want all comments to be combined.

4
Import annotations

Go to the Comments List panel in the destination PDF, click the Options menu, and select 'Import Data File'. Select the data file you just saved to load the annotations into the document.

5
Repeat for additional files

Repeat this export and import process for any other PDF documents whose comments need to be consolidated.

Export and Import Comments Data
Data Format Compatibility: Exported comment data is typically saved in FDF (Forms Data Format), which is standard across most professional PDF editors and stores only the coordinate and text data of the annotations.

Frequently Asked Questions

Can I merge the actual PDF pages along with their comments?

Yes. If you want to combine the pages themselves rather than just extracting the data, you can use a 'Merge PDF' tool. This will combine multiple documents into a single PDF file, retaining all existing annotations on their respective pages.

Why are my imported comments appearing in the wrong place?

Comments are anchored to specific X and Y coordinates on a page. If the destination PDF has different margins, page sizes, or layout structures than the source PDF, the comments will appear misaligned. Always use identical document versions for exporting and importing.

What is an FDF file?

FDF stands for Forms Data Format. It is a lightweight text-based file format used to export data and annotations from a PDF document without including the heavier graphics and text of the actual document pages.
