Online Whiteboard
A free, no-signup drawing canvas for sketching, brainstorming and teaching. Works on desktop, tablet and phone.
How to Use the Online Whiteboard
Pick a tool from the toolbar above the canvas: the pen for freehand strokes, the eraser for cleaning up mistakes, or one of the shape tools for rectangles, ellipses and straight lines. Choose a stroke color from the color picker, drag the size slider to set the stroke width, and start drawing. Every change happens instantly inside your browser; nothing is ever uploaded to a server.
To add labels or notes, click the text tool and then click anywhere on the canvas. A small prompt will appear so you can type the text you want to place. The text inherits the current color and size so you can build a consistent look across drawings, mind maps and quick mockups. If you make a mistake, press Ctrl+Z (or Cmd+Z on macOS) to undo, and Ctrl+Shift+Z or Ctrl+Y to redo. Up to thirty steps are tracked at any time, which is enough for most sketching sessions.
When you are happy with the result, use the Download PNG button to save a transparent or colored version to your computer, or Download JPG if you need a smaller file with a solid background. PNG keeps the transparent option active, while JPG always renders with the current background color so the output looks the same as the canvas. The whiteboard works equally well with a mouse, a stylus or a finger on touch devices, and the canvas resolution adapts to high-DPI screens for crisp lines.
What You Can Do With a Browser Whiteboard
An online whiteboard is one of the most flexible tools you can keep in a browser tab. Teachers and tutors use it during online lessons to explain math problems, draw diagrams, and walk students through step-by-step solutions in real time. The pen and shape tools are enough to recreate most classroom blackboard moments, and the export feature lets you share a snapshot of the lesson as homework or revision material afterwards.
Designers, product managers and engineers reach for a quick whiteboard when they need to sketch a wireframe, draw a flow chart, or roughly plan an architecture diagram before formalising it in a heavier tool. Because everything runs in the browser, there is no installation friction: open the page, sketch the idea, save the PNG and drop it into a Slack thread, an email, a Google Doc or a project ticket. It is the fastest way to turn a thought into a visual.
Beyond work, the whiteboard is a fun creative space. Use it to brainstorm a list of ideas with bubbles and arrows, draw quick illustrations for a blog post, build family bingo cards with the kids, plan room layouts, doodle while on a call, or create a simple thumbnail for a video. The eraser, undo history and unlimited canvas freedom invite experimentation without the pressure of getting it right the first time.
Frequently Asked Questions
Is my drawing saved automatically?
No. To keep things simple and private, the whiteboard does not save your drawing to a server or to local storage. If you close or reload the page, the canvas resets. Always use the Download PNG or Download JPG buttons before you leave to keep a copy of your work. Because nothing is uploaded, you can safely sketch confidential diagrams or rough drafts.
Does it work on touch devices and tablets?
Yes. The whiteboard uses pointer events, so a mouse, an Apple Pencil, a stylus on Android, and your finger on a phone or tablet all work the same way. We disable browser pan and zoom on the canvas so your strokes follow your finger or pen accurately. The toolbar wraps onto multiple lines on small screens to stay reachable.
Can I import an image to draw on top of?
Not currently. This version of the whiteboard is intentionally focused on a clean drawing canvas with no image import. If you need to annotate a photo or screenshot, please save the image, upload it into a dedicated annotation tool, or draw a sketch from scratch on this page. Image import may be added in a future release based on user feedback.
How do I share a drawing with someone?
Use the download buttons to save a PNG or JPG file, then attach the image to an email, message or shared document. PNG is the best choice when you want a transparent background or maximum quality; JPG produces a smaller file with a solid background, which is ideal for chat apps and embedded previews. Real-time collaboration is not part of this tool.
Is there a size limit on the canvas?
The canvas resizes to fill the available width of the page, with a 4:3 aspect ratio. Very large canvases use more memory, especially when you also use undo and redo, because each step stores a snapshot of the drawing. For most use cases this is not an issue. If you notice performance dropping on a long session, save your work and reload the page to start a fresh canvas.
Why does the JPG export show a background even when I picked transparent?
The JPG image format does not support transparency. When you export to JPG, the whiteboard fills the canvas with the current background color (or white, if transparent is on) before saving. If you need transparency, choose Download PNG instead.
