Annotate PDF, Office and Image Files

Annotate PDF, Office & Image Files

With a single GroupDocs.Annotation for Cloud subscription, you can annotate virtually all common business file types without having to install any software. Supported formats include: PDF, Microsoft Word, Excel, PowerPoint, Visio, CAD, JPEG, TIFF, PNG and many more.

Get Documents Approved Faster

Get Documents Approved Faster

Instead of emailing a document back and forth until it is finally approved, invite all involved parties to a shared online review session where everyone can add annotations and reply to others’ comments in real time. Getting documents approved has never been easier before!

Online PDF Annotation

Export to Native PDF Annotations

Annotate documents online, save them for further review, print to get a hard copy, or export to PDF. Comments and markup are burned into the exported files as native PDF annotations so that you can edit them offline with any PDF software.

Share Documents Securely

Restrict downloading, printing and copying of your highly valued documents, while still sharing them with others for online review. Even more, you can add watermarks to protect the shared documents against screen-grabbing and completely hide sensitive data with redactions.
