Add-On Type(s)



HTML5-based document annotator by GroupDocs (.NET version). Adds PDF, Microsoft Office and Image files annotation functionality to your ExpressionEngine website.

Let Users Annotate Documents on Your EE Site

With this plugin you can seamlessly integrate a .NET version of the GroupDocs HTML5-based document annotator into your ExpressionEngine site. It enables your users to view and annotate common document and image types right on your website without having to install any browser plugins or office software. The file formats supported by GroupDocs.Annotation include: Microsoft Word, Excel, PowerPoint, Visio, Outlook and Project; PDF, RTF, CSV, TXT and OpenDocument; CAD and raster images (TIFF, PNG, JPEG, GIF, BMP).

As it stands from its name, GroupDocs.Annotation for .NET is a downloadable .NET library. Unlike the cloud version of our annotation tool, GroupDocs.Annotation for .NET can be deployed on-premises. It allows you to store and host your documents in-house, without the need to expose them to any 3rd party cloud storage providers.

Why GroupDocs.Annotation?

Protects your content from unauthorized copying.
The documents you share and embed to your website via GroupDocs.Annotation are not downloaded to user machines during view/annotation sessions. Instead, GroupDocs.Annotation renders documents in user browsers as a combination of HTML/CSS/images and JS. The download, print and text copy/paste options available to users in the GroupDocs.Annoation UI, can be easily disabled. You can control which documents are published on your site in a read-only mode and which with full access rights.

In addition to that, you can add watermarks over the displayed documents or even redact text and images to protect your content from screen-grabbing.

Provide unmatched document collaboration experience.
GroupDocs.Annotation allows multi-user document review & annotation sessions - users can invite colleagues and partners to comment on a document on your site, see each other’s comments and reply to them in real time. Annotated documents can be then exported to a PDF file or printed out along with the annotations.

Even more, GroupDocs’ annotations placed online are compatible with native Microsoft Word and PDF annotations. This allows users to save annotated Word and PDF documents with added annotations for further offline editing.

Annotate documents anytime, anywhere.
Documents embedded on your site with GroupDocs.Annotation can be viewed and annotated from any device that has an HTML5-compatible browser. Supported browsers include IE8+, Safari5+, Chrome, FireFox, Opera and their mobile versions. There is no need to install any plugins or 3rd party office software. You just embed a document to your EE site and users can view and annotate it right away.

Installing the Plugin
