5 Fun Facts about Doodling & Whiteboards

White eraser is just paint

Most “erasers” on digital boards literally paint white pixels. On transparent canvases, the eraser is just drawing alpha.

Erase illusion

Undo stacks are memory hogs

Every undo snapshot can be millions of pixels. Limiting history (like 30 steps) keeps browsers from ballooning RAM.

Behind the scenes

Straight lines without a tool

Holding Shift while drawing often locks the slope—instant ruler mode without switching tools.

Hidden shortcut

Grids calm the wobble

A light grid lowers “line anxiety” and helps keep forms steady. Architects swear by graph paper for the same reason.

Steady hand

PNG is your friend

Whiteboards are flat art; PNG keeps crisp strokes and tiny text. JPG can blur edges; WebP is good if you want small files.
