Smart Whiteboard
Draw and add shapes, text and images on a whiteboard that runs in your browser, then export it as a PNG or SVG image or save a JSON file to continue later.
Everything stays in your browser: your work is autosaved on this device only, every 5 seconds.
How to use the whiteboard
Great for quick explanations, brainstorming and sketching diagrams — on desktop or mobile.
- Pick "Draw" and sketch with your mouse or finger; change the pen colour and line width under Style.
- Add a rectangle, circle, triangle, line or text, then use "Select / move" to move, resize and rotate it.
- Insert an image from your device to annotate it, and delete any selected item with the Delete key.
- Export your work as a PNG or SVG image, or save a JSON file to import later and keep editing.
Frequently asked questions
Are my drawings uploaded to a server?
No. The whiteboard runs entirely in your browser, and autosave uses your device's local storage only.
What if I close the page by mistake?
The board is autosaved every 5 seconds; when you come back we ask whether you want to restore your last board.
What is the difference between PNG, SVG and JSON?
PNG is a ready-to-share image, SVG stays sharp at any size, and JSON is the project file you can import later.
Why wasn't my work autosaved?
Large images can exceed the browser's local storage space. In that case, save a JSON file manually.
