Free online whiteboard
A free online whiteboard, ready instantly
TempCanvas is a personal browser whiteboard for quick diagrams, visual notes, calculations, and explanations. Open the canvas and draw immediately without creating an account or starting a collaboration room.
Use the whiteboard without signing up
There is no login screen, workspace picker, or installation. TempCanvas opens directly to a blank whiteboard and works with a mouse, trackpad, touch screen, or compatible stylus.
Draw, write, and arrange ideas
Use freehand pens, an eraser, text, rectangles, circles, colors, and adjustable line widths. Paste or upload an image, move and resize objects, then use zoom, undo, and redo while you work.
Keep a temporary whiteboard private
Your current drawing is saved in local browser storage for recovery after a refresh. TempCanvas does not upload it to a cloud document or attach it to an account. Export a PNG only when you decide to keep or share a copy.
A focused personal whiteboard
TempCanvas is designed for one person working in one browser. It does not provide real-time collaboration, shared rooms, cloud projects, or team permissions, which keeps it useful for fast individual thinking.
Is this online whiteboard free?
Yes. TempCanvas is free to use and does not require a paid plan or account.
Can I use the whiteboard without signing up?
Yes. Open the canvas and start drawing. No registration, login, download, or installation is required.
Is this a collaborative whiteboard?
No. TempCanvas is a personal, single-browser whiteboard and does not provide real-time multi-user collaboration.
Where is my whiteboard saved?
The current canvas is stored locally in your browser for recovery. You can export a PNG when you want a permanent copy.
