Free Online Whiteboard & Hand-Drawn Diagram Tool

What is Excalidraw?

Excalidraw is a virtual whiteboard built for the web. It mimics the feel of sketching on paper while offering digital benefits: undo/redo, export, sharing, and real-time collaboration. Unlike pixel-perfect design tools, Excalidraw embraces a rough, hand-drawn aesthetic that encourages ideation over polish. It is widely used for flowcharts, wireframes, technical diagrams, brainstorming, and meeting notes. The tool is free, open source, and runs entirely in the browser.

Features

Excalidraw provides the tools you need to sketch ideas quickly and share them with your team.

Hand-Drawn Style

Elements look sketched by hand. Diagrams feel approachable and easy to understand without sacrificing clarity.

Shapes & Connectors

Rectangles, arrows, diamonds, and more. Smart connectors snap to elements and stay attached when you move them.

Libraries

Add custom libraries for charts, icons, and recurring elements. Reuse assets across projects.

Export Options

Export as PNG or SVG. PNG for presentations and docs; SVG for vector scaling and further editing.

Dark Mode

Toggle between light and dark canvas backgrounds. Reduces eye strain when working for long sessions.

Keyboard Shortcuts

Full keyboard support for power users. Fast copy, paste, align, and transform without touching the mouse.

Tips for Better Diagrams

Use these practices to get more from Excalidraw.

Use the grid

Enable the grid for consistent alignment. Elements snap to grid by default for cleaner layouts.

Group related elements

Select multiple shapes and group them. Move and resize as one unit for faster edits.

Leverage libraries

Add libraries for charts, icons, and recurring elements. Saves time on repeated visuals.

Keep it simple

Low-fidelity works best. Focus on structure and flow rather than decoration.

Use consistent colors

Assign colors by meaning (e.g., green for success, red for errors) to improve readability.

Export at the right size

For PNG, choose a resolution that matches your target (e.g., 2x for retina). For SVG, scale as needed.
