GroupDocs.Annotation for .NET makes the document review, annotation and approval process a breeze. It allows users to annotate over 50 different types of documents and images online, straight on your Orchard website. To name just a few, with this tool users can seamlessly annotate PDF and Microsoft Word documents, Excel spreadsheets, PowerPoint presentations, Visio diagrams, CAD drawings and raster images (TIFF, JPEG, PNG, GIF, BMP).

The GroupDocs.Annotation for .NET library was built from the ground up as a middleware which can be easily customized and integrated into any document management workflow. Thanks to its advanced document annotation features, it delivers unmatched UX in online document review and collaboration. Key features include:

1. Cross-platform compatibility. Users can annotate over 50 common types of documents and images from any web-enabled device and without having to install any office software. All a user needs is a standard web-browser, such as IE8+, Safari5+, Chrome, FireFox or Opera. So, no need to install Adobe Acrobat to be able to annotate PDF documents, for example.

2. Multi-user annotation sessions. Users can invite others for online document review, annotation and approval. During such collaborative document review sessions, users can add annotations, see each other’s comments and reply to them in real time. Documents get approved faster as there is no need to email them back and forth between the involved parties.

3. Support for native Word and PDF annotations. Word and PDF documents annotated online via GroupDocs.Annotation can be saved with annotations in them for further offline editing.

4. Advanced document security. GroupDocs.Annotation works in such a way that original documents are not transferred to users during view/annotation sessions. The library converts documents to a web-compatible content and then streams it to client browsers. In the output, end users see only a copy of the original documents in their web-browsers.

Integrated digital rights management functionality allows you to prohibit unauthorized content copying, printing and downloading. Documents embedded to your website can be shared in a “read-only” mode and protected with passwords. Additionally, you can apply custom watermarks to protect your documents against screen-grabbing or use an in-built redaction tool to completely hide sensitive data.
