Brush
Private by design
A drawing board that feels like a real pen, entirely in your browser
The brush thickness changes as you draw: press harder with a stylus for a bolder line, move fast for a thin stroke, slow down for a thick one, or hold the pointer still and watch the line swell. Your drawing never leaves the page — there is no upload, no account and no tracking, and it keeps working offline after load.
How does the dynamic line thickness work?
With a stylus, the reported pressure maps directly to line width between your minimum and maximum. With a mouse or finger, the width comes from movement speed — fast strokes are thin, slow strokes are thick. Holding the pointer in one spot gradually grows the mark up to the maximum width. The sensitivity sliders control how strongly speed and pressure affect the result.
Which keyboard shortcuts are available?
Ctrl/Cmd+Z undo, Ctrl/Cmd+Y or Ctrl/Cmd+Shift+Z redo, B brush, E eraser, T text. Zoom with Ctrl/Cmd++/−/0, Ctrl+mouse wheel or a trackpad pinch; two-finger scroll pans. The board is boundless — it grows automatically as you zoom out or pan, and saving crops the PNG to what you actually drew.
Is my drawing uploaded anywhere?
No. Everything is drawn on an HTML canvas in your browser. Saving exports a PNG file straight from the canvas to your device — nothing is sent to a server, and there are no trackers.
