Online Whiteboard

How to use it

• Draw by pressing and dragging on the white area with a mouse, finger or pen.
• Colour opens a colour chooser for the pen.
• Pen size makes the line thinner or thicker.
• Eraser switches to rubbing out. Untick it to draw again.
• Undo steps back one stroke at a time, up to 20 strokes.
• Clear wipes the whole board. Undo brings it back.
• Download PNG saves the board as a picture.

Good uses

• Teaching and tutoring: share your screen and draw a diagram while you explain.
• Meetings: sketch a flow, a layout or a rough chart faster than building it in slides.
• Problem solving: work through equations or a sketch by hand.
• Signatures and notes: write something by hand and save it as a picture.
• Children: a simple drawing pad with nothing to install.

Tips for clearer drawings

• Use a pen size of 3 to 5 for writing and 8 or more for headings and shapes.
• Stick to two or three colours, and give each a meaning, such as black for the main drawing and red for corrections.
• Write larger than feels natural. Screen-shared handwriting shrinks for the viewer.
• For straight lines, draw quickly in one stroke.

Limits

• One user at a time. There is no shared or real-time collaboration.
• There are no shapes, text boxes, sticky notes or layers. Everything is freehand.
• The board is a fixed size of 1600 × 900 pixels and cannot be scrolled or zoomed.
• The eraser paints in white, so erased areas are white in the downloaded picture too. The background is not transparent.
• Undo remembers the last 20 actions.
