BPMN Viewer

BPMN Viewer is a lightweight, offline-first browser extension for opening, viewing, and checking BPMN 2.0 diagrams directly in your browser. It is designed for users who want a fast and simple way to inspect workflow files without relying on heavy desktop tools or online services.

With BPMN Viewer, you can open local BPMN or XML files, preview workflow diagrams instantly, inspect the underlying XML source, and export diagrams as SVG or PNG when needed. The extension focuses on a clean and practical experience: drag-and-drop loading, smooth zoom and pan controls, fullscreen preview, dark mode, bilingual English/Chinese interface, and keyboard shortcuts for faster navigation.

BPMN Viewer also helps users work more efficiently when reviewing process files. You can load BPMN content into the built-in XML editor, check the structure, and sync the editor content back to the diagram preview for quick inspection. The extension remembers your workspace state locally, so returning to your last opened content is simple and convenient.

Built with a lightweight and offline-friendly design philosophy, BPMN Viewer keeps the interface simple while still providing the essential features needed by developers, analysts, product teams, and business users who work with BPMN workflows.
