The text is compared, not the look of the pages: changes of fonts, images or layout aren't shown. A scanned PDF has no text; make it searchable with OCR PDF first.


How to compare two PDF files

  1. Drop the original PDF on the left and the changed one on the right.
  2. Their text is compared paragraph by paragraph, and word by word within a changed paragraph.
  3. Read the changes: removed text struck out in red, added text in green; show the whole text, or ignore case and spacing.

Questions

What does it compare?

The text of the two PDFs, in reading order: words added, removed or changed, paragraph by paragraph. Changes of fonts, images or layout aren't compared.

Is it good for contracts?

Yes: it shows every word changed between two versions, so a clause quietly reworded or a number changed stands out.

Can it compare scanned PDFs?

A scan has no text: make both searchable with OCR PDF first, then compare them here.

Are my PDFs uploaded?

No. They're read and compared by your browser, on your device, and never sent anywhere.
