I am recommending GroupDocs because I have found this viewer to be more secure compared to Google docs and the document rendering is quite fast and close to the original.

GroupDocs is a conglomerate of Office tools placed under the same roof and for the sake of understanding, it can be seen as Microsoft Office on the web.

You can add comments and mark up your text in real-time, much like documents in Google Drive.

Whether your organization is large or small, GroupDocs will make your life easier when it comes to working together with colleagues and collaborating on major projects online.

After implementing and using GroupDocs Viewer for .NET in the project it looks to be working very well. I have tested with a lot of documents and so far so good. Everything I've thrown at it renders nicely and looks just as good as it would in a PDF viewer or MS Word.

Excellent service and excellent products. They were extremely helpful and responsive during the GroupDocs Viewer for .NET implementation process, can't recommend them highly enough.

Integrating GroupDocs Viewer for Cloud API was simple with their fantastic Ruby SDK. There aren't that many companies out there who are willing to work with us on what we want. It's a great partnership.

I am excitedly watching the growth of GroupDocs. The responsiveness of your full team has helped me greatly, when I talk to someone at GroupDocs I can guarantee that someone is listening and making things happen.
