Your drawing stays private — nothing is sent to any server.

About this whiteboard

What you can do

Use the toolbar to insert rectangles, ellipses, arrows, lines, text, and freehand drawings. The hand-drawn font gives sketches a friendly, informal look.

Exporting

  • PNG — a flat raster image for sharing or printing.
  • SVG — a scalable vector file for further editing in design tools.
  • JSON — the full editable scene, so you can reload and keep working later.
