Frequently Asked Questions
What types of differences are detected?
The tool extracts text from each page and performs a word-level diff. Added text is shown in green, removed text in red.
Does it compare images or only text?
Currently it compares the text content extracted from each page. Visual differences in images or layout are not detected.
Is there a page limit?
No hard limit. The tool processes all pages in both PDFs, though very large documents may take a few seconds.
