Sketchpad
Freehand drawing with adjustable brush and eraser.
The sketchpad is a simple freehand canvas — pick a color and brush size, draw with your mouse, stylus, or finger, and export the result as a PNG. An eraser tool and single-step undo help clean up quick sketches.
How to use
- Pick a color and brush size, then draw with your mouse or finger.
- Toggle the eraser to remove parts of your drawing.
- Undo removes the last stroke; export saves a PNG.
Common use scenarios
- Quickly sketching an idea to share in a chat or document.
- Doodling or drawing for fun on a touch device.
- Marking up a rough diagram freehand instead of with precise shapes.
- Drawing a simple signature-style image to export as a PNG.

How we verify Sketchpad
How to get a clean export from your sketch.
Undo only steps back one stroke at a time
Each click of undo removes the single most recent stroke — there's no redo and no multi-step history, so if you need to remove several strokes you'll click undo that many times.
The eraser removes drawing, it doesn't change the background
Toggling the eraser switches your next strokes to erase existing pixels rather than add color — it doesn't add a white layer, so erasing over a blank area has no visible effect.
Export PNG captures exactly what's on the canvas
The exported PNG is a pixel snapshot of the current canvas at the moment you click export — anything erased before exporting won't appear in the file, and there's no separate history to recover it afterward.
Before you rely on the result
- You've picked a brush color and size before starting to draw.
- You understand undo only removes one stroke at a time and there's no redo.
- You've toggled the eraser off again after cleaning up, so new strokes draw instead of erase.
- You've exported the PNG before closing the tab, since there's no auto-save.
Who this is for
- Anyone sketching a quick idea to share in a chat or document.
- People doodling or drawing casually on a touch device.
- Anyone marking up a rough diagram freehand.
- People wanting a simple exported PNG of a hand-drawn image.
Real-world examples
Quick idea sketch
Someone explaining a concept in a chat draws a rough freehand diagram, exports it as a PNG, and pastes it directly into the conversation.
Casual doodling
A person on a touch device doodles for a few minutes using different brush sizes and colors, then exports a couple of favorites.
Freehand markup
Someone reviewing a plan draws freehand circles and arrows over a mental picture of the layout, then exports the sketch to attach as feedback.
Limitations
- Undo only steps back one stroke at a time, and there's no redo.
Frequently asked questions
Can I redo after undoing a stroke?
No — undo removes the most recent stroke, but there's no redo to bring it back. Draw the stroke again if you change your mind.
Does the eraser work like a white brush?
No — it removes existing strokes rather than painting white on top, so erasing over an already-blank area has no visible effect.
Is my drawing saved if I close the tab?
No — there's no auto-save. Export the PNG first if you want to keep your drawing.
Can I change brush size or color mid-drawing?
Yes — adjust the color and brush size controls at any time; the change applies to your next strokes, not retroactively to ones already drawn.
