Simple Whiteboard
A quick full-screen drawing canvas for classrooms: pick a pen color and width, sketch with mouse or touch, erase, undo stroke by stroke, and download your drawing as a PNG. Works offline.

How to play
- Choose a pen color and stroke width from the dock above the canvas, or tap Eraser to switch to erasing.
- Draw directly on the white canvas with your mouse, stylus, or finger — each separate touch draws its own line.
- Tap Undo to remove your most recent stroke one at a time, or tap Clear and confirm to wipe the whole board.
- Tap Save PNG to download your drawing as an image file before you close the tab, since nothing is stored automatically.
Open a blank canvas and start sketching right away with mouse, stylus, or a finger on a touchscreen — no sign-up, no setup. Pick a pen color from the six swatches and a stroke width, or switch to the eraser to remove just the parts you don't want. Every stroke you draw is tracked on its own, so Undo always removes exactly the last mark you made, even if you're erasing rather than drawing. Two or more fingers can draw at once on a touch display without their lines crossing into each other, which makes this handy for quick group sketches at the front of a classroom. When you're happy with the result, download it as a PNG to keep, because nothing on this page is saved once you close the tab.
Frequently asked questions
- Does the whiteboard save my drawing automatically?
- No. Nothing is saved to your device or anywhere else — the canvas only exists while the tab stays open. Tap Save PNG before you navigate away or close the tab if you want to keep what you drew.
- Can more than one person draw on the board at the same time on a touchscreen?
- Yes. Each finger or stylus touch is tracked as its own independent stroke, so two or more people drawing at once on a shared touch display will not have their lines interfere with or merge into each other.
- What happens if I tap Clear by accident?
- Clear never wipes the board on a single tap. It opens a confirmation panel asking you to tap 'Yes, clear it' before anything is erased, and you can tap Cancel instead to keep your drawing exactly as it was.
