Why Use It

How It Works
Choose the original PDF and the revised PDF.
The tool extracts and compares the text from both files.
Added and removed text is highlighted for quick review.
Honest Limits
This tool compares the words in each document, not the layout, page design, or images. It works well for spotting wording changes in contracts and text-heavy documents, but it won't flag a moved image or a formatting-only change.
FAQ
Only text. This tool extracts the text from both PDFs and compares it word by word. It does not compare layout, images, or formatting.
Added words are highlighted in green, and removed words are shown in red with a strikethrough.
No. Scanned PDFs have no text layer to extract, so there is nothing for this tool to compare.
No. The comparison runs entirely in your browser. Neither file is uploaded to a server, and nothing is stored.
