Can the Adobe Acrobat SDK Compare Two PDF Files?
Question details
The user wants to know if the PDF Tools .NET SDK or Acrobat SDK provides programmatic access to compare two PDF files.
- Product
- Adobe Acrobat SDK
- Device & OS
- not provided
- Scenario
- A developer or user is exploring programmatic ways to automate the comparison of two PDF document versions.
- Observed behavior
- The user downloaded the PDF Tools .NET SDK samples but cannot find or is unsure if it exposes Acrobat's Compare Files feature.
Verify whether you are using the PDF Tools .NET SDK or the full Adobe Acrobat SDK, as they have different architectures and capabilities regarding document comparison.
Use Acrobat Pro for Interactive PDF Comparison
Since the PDF Tools SDK does not natively expose programmatic comparison, using Acrobat Pro interactively is the most reliable method to compare visual and text differences.
The downloaded PDF Tools .NET SDK samples are completely separate from the desktop Acrobat application. They are designed for specific document manipulations and do not expose the internal 'Compare Files' UI feature programmatically.
Open the Adobe Acrobat Pro application on your computer.
Navigate to the 'Tools' menu and select the 'Compare Files' option.
Click 'Select File' on the left to choose the old version, and 'Select File' on the right to choose the new version.
Click the 'Compare' button to generate a detailed summary report of all changes, additions, and deletions between the two files.
Review Acrobat SDK Documentation for Programmatic Access
If you strictly require programmatic access, you must consult the Interapplication Communication (IAC) APIs within the separate Acrobat SDK.
Easily Compare Documents with WPS Office
While programmatic SDK comparison can be complex and requires expensive licenses, WPS Office provides an intuitive, built-in document comparison tool. You can easily convert PDFs to editable formats and compare versions side-by-side to track every change effortlessly.
- 1. Open WPS Office: Launch WPS Office on your desktop and navigate to the main workspace.
- 2. Convert PDF to Word: If your files are in PDF format, open them in WPS PDF and use the 'PDF to Word' tool so they can be accurately compared textually.
- 3. Access the Compare Tool: Open a document, go to the 'Review' tab in the top ribbon, and click on 'Compare'.
- 4. Select Files: In the pop-up window, choose the original document as the 'Original document' and the revised version as the 'Revised document'.
- 5. View Changes: Click 'OK' to generate a new document that displays a comprehensive markup of all additions, deletions, and formatting differences.
