What is the Drawing App?
The Drawing App is an interactive client-side sketching canvas designed to let you draw, sketch, and wireframe layouts directly inside your web browser. Equipped with basic brush controls and colors, it acts as a digital whiteboard for quick ideas.
This drawing application operates on a local browser canvas element. Because all strokes, pointer coordinates, and canvas drawings are rendered in local memory, your designs, wireframes, and handwritten notes are never sent to external servers.
How to Use the Drawing App
- Choose Your Tool: Select the "Brush" tool to draw lines, or the "Eraser" tool to clean up segments of your sketch.
- Select a Brush Size: Adjust the "Brush Size" slider in the sidebar to control the thickness of your strokes (from 1px to 50px).
- Pick a Color: Click the custom color picker to select a custom hue, or click one of the preset color circles to apply pre-selected shades.
- Create Your Design: Click and drag your cursor (or stylus pen) across the central white canvas to begin drawing.
- Clear or Save Your Work: Click the "Clear Canvas" button to wipe the board clean. Click "Export as PNG" to download your drawing as an image file.
