What is compare pdfs?
Compare PDFs extracts the text layer from two documents and lines them up with a word-quality diff: added lines are highlighted green, removed lines red, and long unchanged stretches are collapsed so you can jump straight to the changes. Line numbers and pages are shown for every difference.
It is a text comparison, not a pixel comparison — perfect for contracts, policies, and reports where the wording is what matters. Everything is computed in your browser; neither file is uploaded.
