How this workspace works
- Choose the first PDF (v1) and the second PDF (v2).
- Compare them in your browser.
- Download the text diff and read what was removed and added.
Compares two PDFs line by line and downloads a text diff of what was removed and added, in order. It cannot see layout, image, font or colour changes, and it cannot diff scanned PDFs. Side-by-side rendering, synchronised scrolling and highlight overlays are not included.
Your file never left this device, so there is no server copy to delete. Download again, start over, or continue with a related tool below.
