Free online whiteboard for hand-drawn diagrams

Sketch flowcharts and diagrams in Excalidraw in your browser. Hand-drawn whiteboard style, libraries, PNG and SVG export—no install. Collaboration on excalidraw.com.

What is Excalidraw on Uwarp?

Excalidraw is an open-source virtual whiteboard for hand-drawn diagrams, flowcharts, wireframes, and meeting sketches. On Uwarp you get the Excalidraw editor in your browser—no install— with shapes, arrows, libraries, themes, and PNG or SVG export. It is a practical draw.io alternative when you want a sketch-like feel instead of rigid boxes. Drawing runs client-side in your session; for hosted collaboration and Excalidraw Plus features, see excalidraw.com.

How to use Excalidraw on Uwarp

From blank canvas to export.

  1. Open the canvas: The editor loads at the top of this page. Pick a tool from the left toolbar or use shortcuts.
  2. Draw shapes and connectors: Drag rectangles, arrows, and lines; bind arrows to shapes so diagrams stay connected when you move them.
  3. Add text and labels: Double-click shapes or use the text tool for titles, steps, and annotations.
  4. Use libraries when needed: Open the library panel for icons and chart blocks, or load a saved scene from the main menu.
  5. Adjust theme and grid: Enable the grid for alignment; switch light or dark mode from the menu.
  6. Export or save: Use Save as image or Export in the main menu for PNG, SVG, or scene files.

Tips for better whiteboard diagrams

Keep sketches readable and fast to share.

  1. Start low-fidelity: Focus on structure and flow first; polish colors and labels after the layout works.
  2. Group related shapes: Group elements you move together—especially in ecosystem or architecture diagrams.
  3. Use consistent stroke colors: Assign meaning with color (errors, success paths) so viewers parse the diagram quickly.
  4. Export SVG for docs: SVG stays sharp in Notion, Confluence, and slide decks; PNG is fine for quick shares.
  5. Try /freehand-draw for SVG paths: Need pure freehand SVG paths? Uwarp also offers /freehand-draw for hand-drawn line art.

Who this is for

Teams that want a fast virtual whiteboard.

  1. Product and design: User flows, wireframes, and workshop sketches without opening a full design suite.
  2. Engineering: Architecture, sequence, and ecosystem diagrams during reviews and incident docs.
  3. Educators and students: Exam-style drawings, concept maps, and classroom explanations in the browser.
  4. Meeting facilitators: Live whiteboard drawing during retros, planning, and remote interviews.
