Are my drawings public?

No. By default, everything is saved in your browser's 'LocalStorage'. If you start a live collaboration session, data is encrypted on your device before being sent to the server, so we cannot see what you draw.

Yes. You can Drag & Drop images from your desktop directly onto the infinite canvas to annotate over them.

Is it compatible with official Excalidraw?

Fully. We use the same `.excalidraw` (JSON) file format. You can export here and open there, or vice versa, without losing data.

Infinite Virtual Whiteboard (Collaborative Sketching)

The Psychology of the "Imperfect Sketch"

When you present a perfect UML diagram with straight lines and corporate fonts, your audience (clients, bosses) unconsciously assumes the design is "finished" and "definitive". This inhibits feedback. No one wants to criticize something that looks done.

Excalidraw, with its "sloppy" (hand-drawn) style, communicates: "This is a work in progress. Help me improve it". It lowers the cognitive barrier for collaboration. Suddenly, everyone dares to opine and move boxes.

Real Collaboration with Real Encryption

Most online whiteboards (Miro, Mural) store your data in their databases in plain text. ZenUtils Excalidraw prioritizes your corporate privacy.

End-to-End Encryption (E2EE): When you share a live session link, the decryption key is in the URL fragment (after the `#`). That part of the URL is never sent to the server. The server only relays encrypted blobs between participants without being able to read them.

Infinite Libraries

Excalidraw has evolved beyond simple squares and circles. Thanks to its vibrant Open Source community, you can import ready-to-use asset libraries:

Cloud Architecture: Official AWS, Azure, Google Cloud, and Kubernetes icons.
Wireframing: Mobile UI components (buttons, inputs, hamburger menus) to prototype apps in seconds.
Electronics: Resistors, logic gates, and Arduino for circuit diagrams.

Export and Portability

Your data is not held hostage. You can export your work in multiple standard formats:

SVG (Scalable Vector Graphics): Ideal for embedding in websites without losing quality when zooming.
PNG: With "Transparent Background" and automatic "Dark Mode" options.
Read-only Link: Generate a URL that others can view but not edit.

Advanced Features for Power Users

Although it looks simple, Excalidraw hides power under the hood.

1. Smart Charts

Copy two columns of data from Excel or CSV and paste them onto the canvas. Excalidraw will detect the data and ask if you want to create a bar or line chart automatically. With sketch style, of course.

2. Scripting Automation

Developers can use the "Developer Console" to manipulate the canvas programmatically. Need to generate 100 boxes connected algorithmically? You can do it with a small JS script.

3. Mermaid to Excalidraw

If you prefer defining diagrams with code (Mermaid.js), Excalidraw has an experimental translator that converts your text code into editable visual elements. The best of both worlds.
