🖊️ Online Whiteboard
Grab a pen and sketch, freehand drawing with colours and an eraser, saved as you go and exportable as a PNG. Private, no account.
A quick sketch pad, draw with the pen, wipe with the eraser, undo strokes, export a PNG. Auto-saved in this browser only.
How the online whiteboard works
A blank canvas for thinking with your hands: choose a pen colour and size and draw freehand, switch to the eraser to wipe, undo strokes one at a time, or clear the board. Your drawing is auto-saved in your browser stroke by stroke, so it's still there when you come back, and you can export it as a PNG to share. It works with a mouse, trackpad or touchscreen/stylus. Under the hood it draws to an HTML canvas using pointer events, which is why the same code handles a mouse, a trackpad and a finger or stylus without any setup, and why the whole thing runs offline with nothing sent to a server.
This is a deliberately simple sketch pad, pen, eraser and colours, for rough diagrams, wireframes and visual notes, not a full diagramming suite with shapes and text boxes (the flowchart maker covers structured diagrams). A stylus or touchscreen makes it far more natural than a mouse. Everything stays on your device.
Frequently asked questions
Is my drawing saved?
Yes, every stroke is auto-saved in your browser, so the board is still there when you return. Nothing is uploaded; clearing your browser data erases it, so export a PNG for anything you want to keep.
Can I use it with a stylus or touchscreen?
Yes. It uses pointer input, so a finger, stylus or pen on a touchscreen works naturally, as does a mouse or trackpad.
How do I undo a mistake?
Undo removes the last stroke; press it repeatedly to step back. The eraser wipes areas you draw over, and Clear empties the whole board.
Can I add shapes and text boxes?
This is a freehand sketch pad rather than a structured diagram editor. For boxes, arrows and connected shapes, use the flowchart maker; for freeform sketching and notes, this is the tool.
What is an online whiteboard good for?
Quick visual thinking, sketching a rough wireframe, jotting an idea mid-call, drawing a diagram to explain something over a shared screen, or scribbling notes freehand. It shines when a shape or arrow is faster than words and you don't want the overhead of a full design app.
What format does the export use, and can I keep drawing later?
Export is a PNG image, ideal for pasting into a doc, chat or slide. The board itself also auto-saves in this browser, so you can close the tab and pick up the same drawing later, but a PNG is a flat image, so save one for anything you need to keep permanently or open elsewhere.
Is anything uploaded?
No, the canvas and your strokes live entirely in your browser.
