Question 1

How do I use the online drawing tool?

Accepted Answer

Pick a pen, line, rectangle, ellipse, or eraser from the tool panel, set the color and line width, then press and drag on the canvas. Touch screens work on phones and tablets; use the mouse on desktop.

Question 2

Can I download my artwork?

Accepted Answer

Yes. Click "Download" above the canvas to save the current canvas as a PNG image. Each item in the history can also be downloaded individually.

Question 3

How do I undo or clear content?

Accepted Answer

Click "Undo" to step back (up to 20 steps are kept). Click "Clear" to wipe the canvas; the cleared content can still be recovered via Undo.

Question 4

Where is the history stored? Is it uploaded to a server?

Accepted Answer

History is stored in your browser local storage, keeping at most 10 pieces, visible only to you and never uploaded to any server. Clearing history supports undo recovery.
