Paint's core tools cover almost everything a quick sketch needs — lines, shapes, freehand strokes, and an eraser.
The pencil draws a thin, hard-edged line. The brush offers several thicker styles — calligraphy, crayon, watercolor — for a softer look. Both follow your mouse or touchpad exactly as you drag.
Rectangle, ellipse, line, and arrow tools draw a clean shape by dragging from one corner to the other. Hold Shift while dragging a rectangle or ellipse to keep it a perfect square or circle.
The eraser replaces whatever it drags over with the background color, not with transparency — worth knowing before erasing on top of a colored area, since it leaves a solid patch behind, not a hole.
| Tool | What it does |
|---|---|
| Pencil | Thin, hard-edged freehand line |
| Brush | Thicker, styled freehand stroke |
| Shapes | Clean rectangle, ellipse, line, or arrow |
| Eraser | Paints over with the background color |
Every shape tool offers three styles: outline only (just the border, using Color 1), outline with fill (border in Color 1, inside filled with Color 2), and fill only (no visible border at all). The line thickness for the outline is set in a small dropdown that appears once a shape tool is selected.
