## Frequently asked questions

### What is an Excalidraw file?

Excalidraw (.excalidraw) is the JSON format of Excalidraw, a popular open-source virtual whiteboard tool. It stores hand-drawn-style shapes, arrows, text and freehand drawings with their sketchy aesthetic, powered by the rough.js library for canvas rendering.

### Are my Excalidraw files uploaded?

No. Diagrams you open from your device stay on your device and are rendered locally. Only the public sample diagram is requested from the server.

### Why do Excalidraw diagrams look hand-drawn?

Excalidraw intentionally uses rough.js to render shapes with a sketchy, hand-drawn aesthetic. This makes diagrams feel approachable and informal, which is why it's popular for wireframes, brainstorming and educational content.
