Viewing Office Files (and 20+ Other Formats)

Ensure reliable, high-fidelity rendering of MS Office file types and 20+ other formats on all platforms and devices, including iOS, web, Linux and Android.

Real-time Collaboration

Have annotations from many users appear on the same Office document in real time while preserving an original version of the file. Manage annotations in a separate XFDF layer. Add roles, permissions or an audit trail.

Annotate

Drop in or remove all types of existing annotations, including stamp, watermark, call-out, comment, free text, signatures and more. And add your own custom annotations and custom appearances.

Preview

Quickly generate compact page-one previews and thumbnails of Office documents, and have these currently viewable in any client for a user to browse through.

Stream In Linearized PDFs

Achieve first page view in seconds even with massive file sizes by streaming linearized PDF content into a client. Restrict downloading on Android to only those pages viewed to reduce data usage.

Add Even More Functionality

Speed time to market with the most complete PDF SDK on the market -- supporting all major platforms, 30+ file formats, and hundreds of unique features.
