A multi-touch drawing board lets you use multiple fingers simultaneously on a touchscreen device to draw on the same canvas. Each finger paints independently, making it perfect for collaborative sketching, playful art creation, or multi-hand drawing exercises. This tool uses Pointer Events to track each touch point separately.

Any device with a multi-touch screen — iPads, iPhones, Android tablets, Android phones, Windows touchscreen laptops, and interactive whiteboards — all support multi-touch painting in this tool. Desktop users with a mouse can still draw with a single pointer. The tool automatically adapts to your input method.

When Rainbow Mode is enabled, each finger touching the canvas gets assigned a unique color from a vibrant palette. This allows multiple people (or multiple fingers from one person) to draw in different colors simultaneously without changing settings. It's great for collaborative art projects and fun drawing sessions!

Click the "Save" button (download icon) in the toolbar, and your drawing will be exported as a high-resolution PNG image file. The file is named with a timestamp for easy organization. All visible content on the canvas — including white backgrounds — is included in the saved image.

Yes! Click the "Undo" button or press Ctrl+Z (Cmd+Z on Mac) to revert your last stroke. The tool maintains an undo history of up to 20 steps, so you can confidently experiment. Each new stroke (from pointer-down to pointer-up) counts as one undoable action.

Click the eraser button (or press the "E" key) to toggle eraser mode. In eraser mode, your strokes remove existing paint instead of adding color. The eraser uses the same brush size setting, so you can adjust its width with the size slider. The brush preview will show a dashed outline when eraser mode is active.

Absolutely! This is a client-side tool — all drawing happens directly in your browser using the HTML5 Canvas API. No internet connection is required once the page loads. Your artwork never leaves your device unless you choose to save and share it.
