About Online Whiteboard
The Online Whiteboard is a free sketchpad that opens instantly in your browser. Draw with a pen or a semi-transparent highlighter, place lines, rectangles, ellipses and arrows, pick any color and brush size, and erase or undo whenever you need. It is built for quick diagrams, wireframe sketches, brainstorms and explanations.
Four canvas backgrounds — white, dark, grid and dots — cover freehand notes as well as aligned diagrams. Shapes can be drawn outlined or filled, undo and redo let you experiment safely, and “Clear” wipes the whole board after a confirmation.
Everything you draw stays on your device: the board is a local canvas, nothing is uploaded and no account is involved. When you finish, one click exports the whole drawing as a PNG image you can share, paste into a document or attach to a ticket.
