About Compare PDFs

Both files are read in your browser, their text is lined up, and the differences are marked: added lines in green, removed lines in red, and inside a changed line the exact words that differ. "Show changes only" collapses the parts that are the same, and the whole comparison can be downloaded as an HTML report to send to someone else.

It compares words, not pictures. A moved logo, a different font, a colour change or a signature image will not show up, and a scanned PDF has no text to compare until it has been through OCR.

How to use it

  1. 1Drop the original PDF on the left and the changed one on the right.
  2. 2Choose whether to ignore capitals or spacing differences.
  3. 3Press Compare, then read the highlighted lines - or download the report.
