Frequently Asked Questions
Does this compare formatting and layout, or just text?
It compares the text content of each document — additions and removals — rather than visual layout differences.
Does anything get uploaded to compare the files?
No — both PDFs are read and diffed entirely in your browser; neither file is sent anywhere.
