Online Whiteboard

Online Whiteboard gives you a big, smooth drawing board in a browser tab. Sketch with a pen that thins and thickens like real ink, mark things up with a see-through highlighter, add lines, arrows, boxes and circles, type text, and stick coloured notes anywhere. The board keeps going in every direction.

Everything you add stays an object you can change later. Pick up a note and move it, drag a box round a group of shapes, recolour, duplicate or delete them. Undo goes back up to 200 steps, and the board saves itself in your browser, so closing the tab by accident doesn’t lose your work.

It suits teachers, students, teams sketching a screen or floor plan, and anyone who thinks better with a pen. Present mode fills the screen for a lesson or a call. Nothing is uploaded and there is no account.

1. Pick a tool from the top row: Pen, Highlight, Shapes, Text or Note. Choose a colour and size in the row just below it.
2. Draw on the board with a mouse, finger or stylus. On a phone, one finger draws and two fingers move and zoom.
3. Press Select to pick things up: tap one item, or drag a box round several, then drag to move them, or press Duplicate or Delete.
4. Under the board, choose “Whole drawing” or “Visible area”, then press Save PNG or Save PDF. Present fills the screen; press Esc to leave.

• Pen with natural line weight: it follows a stylus’s pressure (such as Apple Pencil) where the browser reports it, otherwise the speed of a mouse or finger.
• Highlighter with a wide, see-through stroke that never darkens where it crosses itself.
• Shapes: line, arrow, rectangle and ellipse, with an optional soft fill. Hold Shift for straight 15° angles, perfect squares and circles.
• Text you can edit again later, in four sizes, and sticky notes in five colours whose writing shrinks to fit.
• Select, move, recolour, duplicate and delete, with a drag-box for many items and arrow keys to nudge.
• Endless board with smooth zoom from 10% to 800%: pinch, Ctrl/⌘ + scroll, the zoom buttons, or “fit” to show everything.
• Grid, dots or plain background, on a white or dark board. The plain black ink turns white on the dark board.
• Save PNG (whole drawing at twice the size, or the visible area at your screen’s sharpness) and Save PDF (one page sized to the drawing).
• Keyboard shortcuts: V select, H move, P pen, M highlighter, E eraser, L line, A arrow, R rectangle, O ellipse, T text, N note, Delete, Ctrl/⌘ + Z, Ctrl/⌘ + D.

• The eraser removes whole objects (a whole pen line, shape or note), not just the part it touches. If you remove too much, Undo brings it straight back.
• Double-tap a text or a note with Select to change its words. With the Text or Note tool on, a single tap on one opens it too.
• The board is saved only in this browser on this device, and clearing your browsing data deletes it. Save a PNG or PDF of anything you want to keep or share.
• A PDF holds a sharp picture of the board, so its text can’t be selected or searched.
• Rest your hand on a tablet while writing with a stylus: touches are ignored while the pen is in use, and two fingers never draw.
