DocuVieware Annotations

Main features

Ready-to-use snap-in

For developers looking for a full set, we have bundled standard annotations and commenting features in a ready-to-use snap-in (see the live demo below).


Just like other UI & UX features, annotations are fully customizable and developers can also create their own, adapted to their requirements.

Real-time collaboration

Enjoy the fastest viewer on the market.
DocuVieware provides client/server performance optimization to have a clear and instant overview of what’s happening on the document. Annotations and comments are displayed in real-time in the viewer and the thumbnails.

Secure workflows

Manage annotations by code or by user interaction and set permissions to view, draw, edit, and comment. Include further security processes such as digital signaturespasswords, and redaction.

XML support

Annotations collection can be loaded and saved in XML, a standards-compliant format for annotation interchange.

Annotate 100+ file formats

DocuVieware supports more than 100 file formats including PDF, PDF/A, MS Office, SVG, metafile (WMF, EMF), HTML, email, and raster images (TIFF, JPEG, PNG, JBIG2, JPEG 2000, WEBP, etc.) formats, as well as RAW camera formats. Any file can be saved as PDF, PDF/A, TIFF, and SVG.
