Sketchpad
Draw freehand with a pressure-sensitive brush, on the paper of your choice, then export a PNG. Everything happens in your browser.
Shortcuts: B brush, E eraser, [ and ] size, Ctrl+Z undo, Ctrl+Shift+Z redo.
How it works
A sketchpad is the fastest way to get an idea out of your head: no file to create, no app to launch, just a sheet and a brush. Pick a brush size and color and draw straight onto the page. If you draw with a stylus or a pressure-sensitive touchscreen, the line thickens as you press harder and tapers as you lift off, the way a real pen does. A mouse draws at a steady width, and you can force that steady width for any pointer with the pressure toggle.
The sketch is stored as a list of strokes rather than as a flat image, which is why undo goes all the way back to your first line, why rotating a phone or resizing the window never distorts what you drew, and why you can export the same drawing at double resolution for print. Choose your paper first - blank, ruled, dot, square, isometric, or cross-hatch - and the grid sits under your strokes without ever being erased by the eraser. Everything is drawn and saved in your browser, so it works offline and nothing is uploaded.
Example. Set the paper to isometric at 40 px spacing, pick a 4 px brush, and block out a room in three-quarter view. Switch to the eraser to knock back the construction lines, press undo a few times to walk the drawing back, then export at 2x and print it.
FAQ
Does it work with a stylus or drawing tablet?
Yes. The tool reads pointer pressure, so an Apple Pencil, an S Pen, or a graphics tablet will vary the stroke width as you press. It also reads the pen at its full sampling rate rather than once per frame, so fast strokes stay smooth. A mouse has no pressure and draws at a constant width.
Is my drawing saved if I close the tab?
Yes. The sketch is saved to your browser local storage a moment after each stroke and comes back when you return. It never leaves your device, so clearing your browser data or opening the tool in a different browser will start you on a blank page.
How far back does undo go?
All the way to your first stroke. Because the drawing is kept as a list of strokes rather than as a picture, undo simply removes the last one, and redo puts it back. There is no fixed step limit.
Does anything get uploaded?
No. Drawing, saving, and exporting all happen in your browser on a canvas. Nothing is sent to a server, so the tool works offline and your sketches stay on your machine.
