About:
Nektony VSDX Annotator is a specialized macOS utility for handling Microsoft Visio VSDX files. It enables users to preview diagrams without the Visio application, add annotations and comments, and convert drawings to widely-used formats like PDF, PNG, and SVG. The tool is designed for professionals who need to review and share technical diagrams on systems that lack native Visio support.

Key Features:

Preview VSDX files without Microsoft Visio
Add annotations, comments, and highlights to diagrams
Convert Visio drawings to PDF, PNG, and SVG formats
Batch processing support for multiple files
Intuitive macOS-native interface

Use Cases:

Sharing Visio diagrams with Mac users who don't have Visio installed
Reviewing and annotating technical drawings in collaborative workflows
Converting legacy Visio files to accessible formats for documentation

Alternatives:

Microsoft Visio – Full-featured but expensive and Windows-only; VSDX Annotator is Mac-native and focused on viewing/converting
LibreOffice Draw – Free alternative with limited VSDX support; Nektony offers better format fidelity and dedicated Visio tooling
