Keep your diagram data secure

diagrams.net and our draw.io apps for various platforms do not store your diagram data - our editor is a unique security-first diagramming tool.

• Set data governance options for fine control over extended features.
• Install our offline desktop app, available on Windows, MacOS and Linux.

We participate in the huntr.dev bug bounty program to ensure a high level of professional scrutiny and data security.

Diagram wherever you want

Use whichever cloud platform you prefer to store your diagram files: Google Drive, Microsoft OneDrive, DropBox, GitHub/GitLab, in your browser, or on your device.

No account needed - your diagrams are not locked behind an account.

Use diagrams.net in your browser and on mobile and touchscreen devices.

Integrate diagrams with other software

Store and work with diagrams in Atlassian Confluence and Jira with our draw.io apps. External collaborators don’t need to join your instance, they can view and edit shared diagram files in diagrams.net - no account or diagram format conversion needed.

Embed diagrams in other applications with our draw.io and diagrams.net add-ons:

• Microsoft Office 365 apps and Microsoft Teams
• Google Workplace apps and Google Classroom
• Notion and NextCloud

Plus, many more 3rd-party integrations are available because we are open source.

Advanced: See how to embed the diagrams.net editor in your own application.

Collaborate in real-time with shared cursors

Multiple editors see changes synchronised in real time using Google Drive or Microsoft OneDrive, DropBox, and draw.io in Confluence.

Everyone collaborating on a diagram can see exactly what everyone else is doing.

Easy-to-use diagram editor

diagrams.net and and our draw.io apps work just like the office and drawing tools you are used to using.

• Drag and drop shapes from the shape libraries and drag to draw connectors between them.
• Drag connectors to add waypoints and set a precise shape and position, or let them reroute automatically.
• Double click and start typing to add a label to anything.
• Create tables and swimlane flows with a familiar tool.
• Style shapes and connectors with customisable palettes, sketch options, fonts and text formatting tools.
• Search for shapes, including in open-source icon libraries.
• Use our vast libraries of shapes and templates, organised into logical categories, to create a range of diagrams and infographics.
• Diagram faster with keyboard shortcuts.
  
  

Diagram your way: Find your favourite editor theme - a simple online whiteboard, floating tool panels, dark mode, or the standard diagramming software layout. You can also switch the editor to use your language.

Import and export: Drag and drop a file to import a diagram, including many other diagram formats and continue editing. Publish and export to many formats.

Many advanced and helpful tools are built into the diagram editor.

• Use the infinite canvas, rulers, customisable grid and positioning guidelines to help you diagram faster.

• Organise your diagram with layers and tags. Set shape properties, metadata and placeholders to add translations, tooltips, links, and interactive actions.
• Sketch and comment with freehand shapes.
  
• Create your own custom shapes and custom shape libraries.
• Format text with HTML and use mathematics typesetting in labels.
• Generate diagrams text using PlantUML or Mermaid code, CSV spreadsheet data and formatting information, or SQL code.

Tip: If you use draw.io in Confluence, you can mass import all the Gliffy diagrams in your instance in one step.
