How to Compare PDF Files Online
Document comparison is a critical task for legal professionals, students, and writers. Our PDF Comparison Tool simplifies this process by highlighting the exact differences between two versions of a document. Whether you are tracking changes in a contract, checking for revisions in a manuscript, or verifying data integrity, this tool provides an instant, visual analysis.
Step-by-Step Guide
- Step 1: Upload the Original File. Click on the left box labeled "Original Document (A)" to select your first PDF file. This serves as the baseline for comparison.
- Step 2: Upload the Modified File. Click on the right box labeled "Modified Document (B)" to upload the second PDF. This is the version you want to compare against the original.
- Step 3: Analyze Differences. Once both files are uploaded, the "Compare PDFs" button will activate. Click it to process the documents. The tool will extract the text and generate a side-by-side comparison.
Understanding the Results
The results section uses a color-coded system to make changes obvious at a glance. Text highlighted in Green represents content that has been added to the new document. Text highlighted in Red indicates content that was removed from the original. Unchanged text remains standard black, providing context for the revisions.
