Compare two versions of a PDF file

You can use the Compare Documents feature to find differences between two PDF files. After comparing two files, Acrobat DC provides a detailed report of every change, including text, fonts, images, and even the order of the pages.

  2. Choose the documents to compare. You can limit the comparison to a portion of the documents by entering the page numbers in the First and Last page fields under each filename.

    differences between the graphic elements, select Compare Text Only. Click OK.
