How does the comparison work?

The tool extracts text from both PDFs, compares line by line, highlighting differences: green for added content, red for deleted content.

Can scanned PDFs be compared?

Scanned PDFs contain images rather than text, so text differences cannot be directly compared. Please use an OCR tool to convert to a searchable PDF first.

How accurate are the comparison results?

The tool compares text content, ignoring format differences. If documents have the same content but different formatting, they will be shown as having no differences.

Are multi-page documents supported?

Yes. The tool compares all pages of the entire document, showing an overall difference summary and detailed comparison.

Can comparison results be exported?

The current version displays comparison results in the browser. You can take screenshots or use the browser print function to save as PDF.
