Free Online Whiteboard Tool

1. Pick a pen colour and size, or switch to the eraser.
2. Draw on the canvas with mouse, trackpad or pen input.
3. Use Undo to step back, or Clear to start fresh.
4. Click Download PNG to save your drawing before closing the tab.

Sometimes you just need to draw something — a diagram for a stand-up, a wireframe sketch for a teammate, a quick mind-map. This whiteboard renders to an HTML5 canvas with pointer events, so it works equally well with a mouse, trackpad or stylus. Pen colour and size are selectable from a small palette; the eraser paints white over previous strokes.

Teachers walk students through a problem on a shared screen. Engineers sketch a system diagram during a 1:1. Remote teams use it as the digital equivalent of a meeting-room whiteboard. Undo keeps the last 20 strokes via canvas snapshots; Clear resets the canvas to white; Download exports the current canvas as a PNG.

Nothing leaves your device — there's no cloud, no account and no auto-save. Close the tab and the drawing is gone unless you've downloaded it.
