ToolwebHow to use this tool
- Choose a pen, line, rectangle, ellipse or text tool, then set its color and width.
- Draw on the canvas or add an object at the center, then arrange it with Select / move.
- Save the result as PNG, or save project JSON separately to continue editing later.

- Result
- A 1200×800 board; move objects or edit labels, then export a PNG at that size
The editor grid, selection outline and keyboard cursor are excluded from the PNG.
Draw and select objects
A pen stroke, shape or text block is treated as one object. Select / move chooses the topmost object under the pointer and lets you drag it. Erase removes a complete selected stroke or shape rather than rubbing out individual pixels.
Add text by writing in the text field and placing it on the canvas. Selecting existing text loads its contents into that field; apply the selected-object settings to commit an edit. A focused canvas also accepts arrows and Enter for drawing and moving selected objects.
Saving and board limits
PNG flattens the current board onto its background color. Project JSON retains object types, coordinates, colors and text for later selection and editing. Importing replaces the current board but Undo can restore its previous state; there is no autosave or collaborative editing service.
Canvas sides range from 200–3000px with a nine-million-pixel maximum. Limits are 500 objects, 50,000 total pen points, 2,000 points per stroke, 500 characters per text object, and 4MB per project file. The latest twenty changes can be undone; shrinking a canvas warns when objects would extend outside it.
Common questions
Will the board remain after I close the page?
The board is not automatically retained: closing or reloading clears the tab’s work. Save project JSON yourself for future edits and download a PNG when you need a finished picture to share.
Will the page scroll while drawing by touch?
The drawing surface prevents touch strokes from turning into page scrolling. Scroll the page outside the canvas, or use view zoom and the board’s scroll container to inspect a large drawing.
