From the developer:
Add a simple PDFviewer to your next project with an easy-to-use enhancement from IronSoftware. PDF Viewer Tools elevates your application by adding PDF capability beyond simple reading. You can also add, delete, combine, merge, and batch PDF files for simple manipulation inside of your device. Instead of having to rely on bloated third-party applications, everything is done natively using C# or HTML. This adds more value to your next app.
