Info updated on:

PDiff Express 2 is an application that finds differences and similarities between two PDF files. Therefore, you will be able to see at a glance what has changed within the revised version of the original document so you can act accordingly. The tool works with all types of text, no matter if they are fictional or non-fictional, scientific or financial, personal or made for business purposes.

Using the application isn't difficult at all. Once the documents are loaded, the differences are automatically highlighted and reported in a table-like preview. You can set from Preferences favorite colors for the matching words, the replaced text, the inserted characters, and for other types of changes. Hovering the mouse over the text highlights the corresponding words for an accurate comparison of the documents. However, the utility doesn't identify only word changes, but also layout modifications, font-related changes, inserted page breaks and newly added hyphenation. Optionally, you can compare specific pages of multi-page PDFs and leave the other pages unprocessed.

To conclude, PDiff Express 2 is a smart application that compares PDF texts and pinpoints the differences. It is ideal for checking scripts modified successively by different users so you can see each one's contribution to the original text.
