# About the Difference Detection Plug-in

You can use the difference detection plug-in to compare two documents of the same format (extension) and view the differences in a web browser.
You can compare documents in two different modes: image comparison mode, where pages are converted into images, and text comparison mode, where the text is extracted.
The plug-in detects differences in the following types of documents:

- DocuWorks documents (. xdw)
- DocuWorks binders (. xbd)
- PDF file (.pdf)

Note
Use Google Chrome or Microsoft Edge as the web browser to view the differences. To change the web browser to use, change the default browser.
