This plugin hasn’t been tested with the latest three major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

GroupDocs.Annotation for Cloud


GroupDocs.Annotation for Cloud plugin lets you embed different types of documents and images into your website and then invite your colleagues and clients to view and annotate them online, without the need to install any document editors or browser plugins.

While modern document editors have built-in tools for annotating documents through comments and tracking changes, the conventional way of working on documents has become too slow and bulky for today’s business pace. New cloud services such as GroupDocs.Annotation streamline this process and offer new and more efficient ways of collaborating with your team.

No need to install any document editors.

While it may still be okay to ask your team members to install the same piece of software to work on documents and images together, you don’t want to force your clients to do the same if they need just to review and annotate a PDF document, for example. Rather than offering them to find and install a PDF annotation tool, you can invite them to do this on your website with a usual web browser without any special plugins.

No compatibility issues.

Even if your team members already have document and image editors for other tasks, they may prefer different types of software, which may cause compatibility problems. With GroupDocs.Annotation you can be sure that your colleagues and partners will see your document exactly the way you see it on your computer.

Real-time collaboration.

Instead of waiting for an e-mail from each of your team members with their feedback on a document, you can invite them to annotate it on your website in real time. This can make a difference if you have a close deadline and need to get feedback and approval instantly.

Absolutely mobile.

Now you don’t need to check your e-mail, then download the attached document and open it in a specific program to be able to view and annotate it. GroupDocs.Annotation will allow you to do this on any mobile device while you are on the go.

Different types of documents and images supported.

GroupDocs.Annotation plugin allows you to annotate PDF documents, Excel spreadsheets, word-processing documents, PowerPoint presentations and image files (JPG, BMP, GIF, TIFF) online.
