How to find the differences between two PDFs

Reading a returned contract line by line to find which clause changed is tiring and risky. The PDF comparison tool matches the text of two documents sentence by sentence and shows only the differences.

Added sentences are green; removed ones are red and struck through. For a small edit, such as a changed amount or date, only the changed words are marked rather than the whole sentence. Each difference shows its page number.

The comparison looks at text; images and page layout are not compared. If one document is a scan, run it through the OCR tool first. Word, text and EPUB files can be compared too.
