The Professional PDF Comparison Workflow
Upload Both PDFs
Upload the original PDF to the left drop zone and the modified version to the right. Both documents are required for comparison.
Configure Comparison
Choose comparison mode — text & content, visual layout, or both. Adjust sensitivity to control how detailed the diff analysis is.
Review Differences
Navigate through pages and review highlighted changes. Additions appear in green, deletions in red, and modifications in yellow.
Export Results
Download the comparison report as a PDF with embedded diff highlights, or export a summary of all detected changes.
Comparison Expert Advice
- Use "Both" mode for comprehensive comparison that checks both text content and visual layout changes.
- Lower sensitivity helps filter out minor formatting differences like font size changes or spacing adjustments.
- For contract or legal document review, use "Text & Content" mode to focus on substantive wording changes.
- Always verify detected differences at full zoom, especially for complex layouts with tables and columns.
