Question details
The user needs to resolve an issue where Adobe Acrobat DC fails to compare two documents, instead placing them in a portfolio and showing a single-document error.
- Product
- Adobe Acrobat DC
- Device & OS
- not provided
- Scenario
- Attempting to compare two PDF files using the Compare Documents tool in Acrobat DC.
- Observed behavior
- Acrobat creates a portfolio containing both files and displays an error stating the portfolio is only one document and cannot be compared.
Ensure you are using the original, unencrypted PDF files rather than files already embedded within a PDF package or portfolio. Check if your Adobe Acrobat DC is updated to the latest version.
Use Original PDF Files Directly
Avoid placing files into a portfolio before comparison, as Acrobat's Compare tool requires independent files to function correctly.
The Compare Documents tool in Adobe Acrobat is designed to analyze two distinct, independent PDF files. If the files are placed into a PDF portfolio first, Acrobat treats the portfolio container as a single file, triggering the error.
If your files are currently inside a portfolio, extract or save the two PDF files you want to compare to a local folder on your computer.
Open Adobe Acrobat DC and navigate to 'Tools' > 'Compare Files'.
Click 'Select File' on the left side of the screen to choose the first original PDF document from your local folder.
Click 'Select File' on the right side of the screen to choose the second original PDF document.
Click the 'Compare' button to run the tool without triggering the portfolio error.
Check for Structural Features or File Corruption
Files containing existing portfolio, package, or complex structural features may prevent the Compare tool from working.
Use WPS Office to Compare PDF Documents Side-by-Side
Instead of dealing with complex portfolio errors in Acrobat, you can use WPS Office to open and compare your PDF files side-by-side effortlessly. WPS Office provides a lightweight and highly compatible PDF reader and editor.
- 1. Download and Install WPS Office: Download WPS Office for free from the official website and install it on your computer.
- 2. Open Your PDF Files: Launch WPS Office and open the two PDF documents you want to compare. They will open in separate tabs.
- 3. Enable Side-by-Side View: Go to the 'View' tab in the top ribbon and select 'View Side by Side' to display both PDFs simultaneously on your screen.
- 4. Compare the Documents: Scroll through the documents to visually compare the text and layouts without any portfolio restrictions.
Frequently Asked Questions
Why does Acrobat say my PDF portfolio is only one document?
A PDF portfolio acts as a container or envelope for multiple files. Acrobat's Compare tool reads the container itself as a single file, which is why it cannot compare the contents inside it directly.
Can I compare documents inside a PDF portfolio?
No, you must first extract the individual documents from the portfolio, save them as standard PDF files on your computer, and then run the Compare tool on those extracted files.
What should I do if the Compare tool still fails on standard PDFs?
The files might have structural issues, security restrictions, or corruption. Try 'printing' the PDFs to a new PDF file using a virtual PDF printer to flatten them, then compare the flattened versions.
