Download draw.io Desktop – Free Offline Diagram and Flowchart Editor

draw.io Desktop is the offline, open-source desktop application version of the popular draw.io (now known as diagrams.net) diagramming tool. It brings the full power of the web-based diagram editor to your desktop, allowing you to create flowcharts, network diagrams, UML diagrams, entity-relationship diagrams, org charts, mind maps, and more — completely offline without a browser.

Built with Electron, draw.io Desktop offers the same rich feature set as the web version including a vast shape library, smart connectors, custom styling, layers, and export options — while adding the benefits of native desktop performance and local file storage. Your diagrams are saved as XML files that can be opened anywhere draw.io is available.

draw.io Desktop integrates with popular platforms including Confluence, Jira, GitHub, and Google Drive, and supports export to PNG, SVG, PDF, HTML, and XML formats. It is trusted by millions of developers, architects, and business analysts worldwide for technical documentation and visual communication.
