How to use Whiteboard / Sketchpad
Three steps, and nothing to install.
Pick a brush colour and size
Set both before you start, since there is no undo to fall back on.
Draw with mouse, touch or stylus
All three input types work on the canvas.
Download your sketch
Save as PNG before leaving the page, since nothing persists after a refresh.

How this works in your browser
Drawing is handled by tracking pointer movement and stroking line segments onto a canvas between successive positions, with rounded line joins so a fast movement still reads as a smooth curve rather than a chain of visible segments. Mouse, touch and pen input all arrive through the same pointer events, which is why a stylus and a finger behave identically. The canvas holds only the resulting pixels rather than a list of strokes, which is what makes rendering instant and equally what makes undo impossible without a different architecture. Nothing is stored beyond the open page and nothing is transmitted, so the download is the only persistence there is.

Frequently asked questions
What it can and cannot do, and what happens to your files.
Does it work on touchscreens?
Yes, the canvas supports both mouse and touch input for drawing.
Can I undo a stroke?
This version does not include undo - use "Clear" to start over completely.
What format does it download as?
A PNG image of the current canvas contents.
Will my drawing survive a page refresh?
No, and this is worth knowing before you invest an hour in something. The canvas lives only in the open page, so refreshing, navigating away or closing the tab loses it entirely. Download as you go if the sketch matters.
Why is there no undo?
Because the canvas stores finished pixels rather than a list of strokes, so there is no record of where one stroke ended and the previous began. Supporting undo means keeping snapshots or a stroke history in memory, which is a meaningfully different tool. Clear and restart is the honest option here.
Does it work with a stylus or drawing tablet?
Yes, since touch and pen input are both handled. Pressure sensitivity is not, so line width stays constant at whatever you set rather than varying with how hard you press.
Is my drawing uploaded anywhere?
No. Everything happens on a canvas in your browser tab, so a sketched diagram of something internal is never transmitted.
