About Annotation app

Microsoft PowerPoint is a widely used software to create presentations containing text, images, animations, and videos. A good presentation is a critical element of any communication effort.

Annotations allow users to collaborate, review documents, and add information according to context. They enable reviewers to offer feedback, editors to propose changes, and collaborators to communicate without modifying the original text.

GroupDocs.Annotation is a fast and efficient API to annotate documents of over 35 different types. Powered by a high-performance cloud-based GroupDocs server, it allows annotating the PPTX files in the browser.

This free online application based on the GroupDocs.Annotation API annotates the PPTX files on your device. Even if your file is encrypted, you can enter a password and view the file. We value your privacy, so the file and the specified password are visible to you only. The application works on any device, including smartphones.
