In addition to the graphics-based comparison with d’accord, we now offer a text-based comparison of PDF documents. Our new software PDiff Express allows you to compare versions of PDF files quickly and reliably in order to find textual similarities and possible changes.

The text-based comparison of document versions with PDiff Express works even if the layout has been heavily modified: changes in fonts, text wrapping, hyphenation, column and page breaks are handled by PDiff Express. Thus you can even compare copy-text with print-ready layouts.

PDiff Express is an ideal solution for versions of documents, technical manuals, legal text and business contracts, financial reports, manuscripts and academic papers for which the amount of textual revision is to be determined precisely.

We provide a free demo version of PDiff Express at
