Compare PDF Files
Compare two PDFs by extracted text page by page. Spot wording changes privately in your browser, no upload.
Diff two PDFs without uploading them
Load a before and after PDF, compare extracted text page by page, and see which lines appear only on one side. Useful for contract revisions and report drafts — kept entirely on your device.
What you can do with it
- Review a redlined contract
- Spot wording that changed between versions when you only have PDFs.
- Check a regenerated report
- Confirm numbers and headings still match last month’s export.
How to compare two PDFs
- Open the left (before) PDF, then add the right (after) PDF.
- Click Compare text and browse pages that differ.
- Optionally download the full diff as JSON.
Text-first comparison
Many “PDF diff” tools upload both files. This compare extracts text per page locally and highlights lines that appear on only one side — ideal for wording changes in contracts and reports.
What it will miss
Pure layout moves, font swaps, or image replacements without text changes may not show. For visual proofing, export pages to images and review side by side.
