Drawing Board - Free Online | FunToolX

After opening the page, a blank canvas is displayed, and on the left is the toolbar: brushes, erasers, lines, rectangles, circles, text, fill, etc. After selecting the brush, you can adjust the thickness, color, and transparency. Support layer management, undo and redo, canvas zoom and pan. Export to PNG, JPEG, or SVG when completed.

The drawing board is implemented based on the Canvas 2D API. The brush collects coordinates through the mousemove/touchmove event and uses the Bezier curve to smooth handwriting. Eraser uses globalCompositeOperation = 'destination-out'. Use fillText for text. All run locally in the browser.

Suitable for quickly drawing sketches, flow charts, mind maps, or making annotations on screenshots. It is also used for blackboard writing demonstrations in teaching scenarios or whiteboard discussions in meetings.

Online artboard tool provides canvas and brush tools, supports multiple brushes, colors, and thicknesses, and can export pictures for sketching and annotation.
