About the Online Whiteboard
Online Whiteboard is a free drawing board that opens instantly in your browser. Pick a pen, eraser, line, box or oval, choose a colour and thickness, and draw with a mouse, a finger or a stylus. Switch between white, grid and dark paper, undo and redo as often as you like, go full screen for teaching or explaining, and download your board as a PNG. Nothing is uploaded and there is nothing to sign up for. A drawing lasts until you leave or reload the page, so download it when you are done.

What a whiteboard is good for
A quick sketch often explains an idea better than a paragraph. People use online whiteboards to explain maths in a video call, plan a layout, sketch a diagram for a colleague, play drawing games or think through a problem. Because the page opens at once without an account, it works for the moments when you just need space to draw.
Pen, shapes and eraser
The pen draws smooth freehand lines. Line, Box and Oval make neat shapes that follow your pointer while you drag. The eraser is wider than the pen so you can clear areas quickly. Start thin for details and increase the thickness for headings and arrows.
- Thin pen for notes and details
- Thick pen for headings and arrows
- Line tool for straight arrows and underlines
- Box and Oval for diagrams and highlights
Paper and colour choices
White paper suits printing and documents. Grid paper helps with graphs, tables and straight diagrams. Dark paper is easy on the eyes in the evening and makes bright colours stand out; switch the pen to white or a bright colour there.
Teaching and presenting
Press Full screen, share your screen in your meeting tool and draw as you talk. Download the board when you finish and share the PNG with your class or team. For text-based diagrams, such as processes and timelines, the Flowchart Maker and Mind Map Maker draw tidy results from a few lines of text.
Save and share
Download PNG saves the whole board with its paper. Reduce the size with Compress Image before emailing, and add captions with Add Text to Image. If you prefer to speak your ideas, record them with the Screen Recorder while you draw.

Frequently asked questions
Does the whiteboard work on a phone or tablet?
Yes. Touch and stylus drawing work, and the board scrolls normally outside the drawing area. Full screen gives a bigger canvas on a tablet.
Is my drawing saved?
Not on our servers. The board lives in the page, so reloading or closing it clears the drawing. Press Download PNG to keep a copy.
Can several people draw at the same time?
No. This is a single-user board that runs only in your browser, which is why it needs no account. For teaching, share your screen and draw while others watch.
How do I draw a straight line or a shape?
Choose Line, Box or Oval, press where it should start and drag to where it should end. The shape follows your pointer until you let go.
How does the eraser work?
It removes ink under it, so the paper colour or grid shows through. It is three times wider than your pen setting. Undo also brings back anything you erased.
Can I change the background after drawing?
Yes. Switching between white, grid and dark paper keeps your drawing, but pick a pen colour that shows on the paper you want, since black ink is hard to read on dark paper.
What is the maximum drawing size?
The board is a fixed 1600 by 1200 pixel page. Downloads keep that full size, so they stay sharp even if you drew on a small screen.
Does it need an internet connection?
Only to load the page. Once it is open, drawing works without sending anything online.
