A whiteboard makes complicated points clear: a diagram for a student, a quick sketch for a customer or a mind map for yourself. No signup is needed.
Quick answer
Draw with a mouse, finger or stylus. Choose the pen colour and size, use the eraser, undo your last strokes or clear the board, and download as a PNG when done.
What to use it for
- Teaching and tutoring maths, science and diagrams.
- Brainstorming and mind maps.
- Explaining a route, a floor plan or a process.
- Sketching a design before building it.
- Signing and marking a simple picture.
Steps
- Open the board and pick a colour.
- Choose the pen size.
- Draw; use the eraser for corrections.
- Press Undo to remove the last strokes.
- Download as PNG to share.
Tips for clear drawings
- Use few colours: black for text, one colour for emphasis.
- Draw big. Small writing is hard to read when shared.
- Keep a grid or clear structure: boxes and arrows.
- For a tablet, use a stylus for more precise lines.
- Take a screenshot or download before you clear the board.
Limits
This is a single-user board. It does not sync between devices or let several people draw at once. Your drawing stays in your browser until you download it.
