Drawing on your computer means using software that lets you create images with a mouse, trackpad, or stylus

You can draw on a computer using programs that come free with Windows or Mac, or by downloading free software like GIMP or Krita. Most drawing programs work the same way: you pick a brush or pencil tool, choose a color, and click or drag across a canvas to make marks. The main difference between programs is how many tools they offer and how much control you have over things like brush size and opacity.

If you have a Windows computer, you already own Paint, which opens from the Start menu and lets you draw with basic brushes and shapes. Mac users have Grapher and Preview, both of which can create straightforward drawings. If you want more features—like layers, which let you draw on separate transparent sheets stacked on top of each other—you will need to read a free program instead.

Key Takeaways

  • Windows Paint and Mac Preview are free drawing programs that come with your computer and work for straightforward sketches and basic designs.
  • GIMP and Krita are free downloads that offer layers, more brush types, and tools for digital painting that rival paid software.
  • A mouse or trackpad works for drawing, but a stylus or graphics tablet gives you much better control and feels more like drawing on paper.
  • Most drawing programs use the same core tools: a brush or pencil, a color picker, an eraser, and a selection tool to move or edit parts of your drawing.
  • Saving your work as a PNG or JPEG file preserves your drawing so you can open it later or share it with others.

Starting with Windows Paint or Mac Preview

If you want to draw right now without downloading anything, open Paint on Windows by typing "Paint" into the search box at the bottom left of your screen, then clicking the Paint app. On Mac, open Preview by clicking the Finder icon, going to Applications, then Utilities, then Preview. Both programs open with a blank white canvas ready for drawing.

In Paint, look for the Brushes section in the top menu. Click on a brush style—Calligraphy Brush, Marker, or Pencil are good starting points—then click on a color in the color palette below. Now click and drag on the white canvas to draw. If you make a mistake, press Ctrl+Z (Windows) or Command+Z (Mac) to undo. Paint also has a shape tool that lets you draw rectangles, circles, and lines by clicking and dragging.

Preview on Mac works similarly but is simpler. Click Tools in the top menu, then Sketch, then choose a pen style. Select a color from the color picker, and draw on the canvas. Preview is best for quick sketches rather than detailed artwork because it has fewer brush options than Paint.

Downloading GIMP for More Control

GIMP (GNU Image Manipulation Program) is a free read that gives you professional-level drawing tools without paying anything. Go to gimp.org, click read, and follow the instructions for your computer type. The read takes a few minutes, and installation is automatic.

When you open GIMP, go to File, then New, and choose a canvas size—start with 800 by 600 pixels if you are not sure. Click Create. On the left side of the screen, you will see the Toolbox. Click on the Paintbrush tool (it looks like a brush), then click on the foreground color square (the black square in the toolbox) to pick a color. Now draw on the white canvas in the center.

GIMP's biggest advantage is layers. In the Layers panel on the right side, you can click the plus icon to add a new layer, then draw on it without affecting your earlier work. This means you can sketch rough outlines on one layer, add details on another, and erase or hide layers without losing anything. To save your work, go to File, then Export As, and choose PNG or JPEG format.

Using Krita for Digital Painting

Krita is another free read designed specifically for digital painting and drawing. Go to krita.org, click read, and install it the same way you would GIMP. Krita feels more natural if you are used to drawing on paper because its brushes are designed to mimic real pencils, charcoal, and paint.

Open Krita and go to File, then New, to create a blank canvas. The left panel shows your brush options. Click on a brush—Pencil, Ink Pen, or Chalk are good for starting—then click on the foreground color to pick a color. Draw on the canvas by clicking and dragging. Krita also uses layers, which you can add from the Layers panel on the right.

One feature that makes Krita popular is its brush engine. You can adjust how a brush behaves by changing settings like opacity (how see-through the color is), flow (how much color comes out), and size. These controls are in the Tool Options panel at the bottom left. Start with the default settings and change them only if you want to experiment.

Choosing the Right Input Device

Drawing with a mouse or trackpad works, but it is frustrating because you cannot tilt the tool or explore pressure the way you would with a real pencil. If you plan to draw regularly, a stylus or graphics tablet makes a huge difference.

A stylus is a pen-shaped tool that works with a touchscreen or graphics tablet. Graphics tablets range from small (about the size of a notebook) to large (the size of a desk pad). When you move the stylus on the tablet, a cursor moves on your screen, and the pressure you explore affects how thick or dark your line is. Budget tablets like the Wacom One or Huion Pen Tablet cost between $40 and $80 and work with GIMP, Krita, and most other drawing software.

If your computer has a touchscreen, you can draw directly on the screen with a stylus designed for that purpose. iPad users can draw with the Apple Pencil in apps like Procreate or Ibis Paint. On Windows, some tablets and laptops have stylus support built in—check your device's specifications to see if yours does.

Understanding Brushes, Colors, and Layers

Every drawing program has a brush tool that works the same basic way: you pick a brush shape, set a color, adjust the size, and drag across the canvas. Brush shapes range from hard-edged (like a pencil) to soft-edged (like a marker or airbrush). Most programs let you change brush size by scrolling with your mouse wheel or using a slider in the tool options.

Colors are picked from a color picker, usually a square or circle that lets you choose hue (what color), saturation (how pure the color is), and brightness (how light or dark). Click on the foreground color in your toolbox to open the color picker. You can also type in a hex code (a six-character code like #FF5733) if you know the exact color you want.

Layers are transparent sheets stacked on top of each other. When you draw on a layer, you only affect that layer—the layers below stay unchanged. This lets you sketch rough shapes on one layer, add details on another, and erase mistakes without starting over. To add a layer, right-click in the Layers panel and choose New Layer, or use the plus icon.

Saving and Exporting Your Drawing

When you finish drawing, you need to save your work. Most programs distinguish between saving (which keeps your layers and editing ability) and exporting (which flattens everything into a single image file).

In GIMP and Krita, go to File, then Export As, and choose a format. PNG is best if you want to keep a transparent background (useful for putting your drawing on top of other images). JPEG is best if you want to share your drawing as a photo or email it, because JPEG files are smaller. BMP and TIFF are less common but work the same way.

If you think you might edit your drawing later, also save it in your program's native format. In GIMP, that is XCF. In Krita, that is KRA. These formats preserve all your layers so you can go back and change things. To do this, go to File, then Save As, and choose the native format.

Common Mistakes and How to Avoid Them

The most common mistake is drawing on the wrong layer. If you add a new layer and then draw, but your drawing does not show up, check the Layers panel to make sure you are on the right layer. Click on the layer you want to draw on to select it (it will highlight in white).

Another mistake is forgetting to flatten your image before exporting as JPEG. If you export a multi-layer drawing as JPEG, the program will automatically flatten it, but you cannot undo that in the JPEG file itself. Always export as PNG first if you want to keep your layers, or save as XCF or KRA before exporting as JPEG.

A third mistake is using a brush that is too small or too large. If your brush is too small, every stroke takes forever. If it is too large, you lose control. Start with a medium brush size (around 20 to 50 pixels) and adjust from there. You can change brush size while drawing by holding Ctrl and scrolling your mouse wheel, or by using the size slider in the tool options.

Finally, do not be afraid to undo. Press Ctrl+Z or Command+Z as many times as you need. Most programs remember your last 20 to 100 actions, so you can go back quite far if you make a mistake.

Frequently Asked Questions

Can I draw on my computer without a graphics tablet?

Yes. A mouse or trackpad works for drawing, though it is harder to control than a stylus or tablet. Start with your mouse and see if you enjoy drawing. If you do, then invest in a graphics tablet later. Many people create beautiful artwork with just a mouse.

What is the difference between Paint and GIMP?

Paint is simpler and comes free with Windows, but it has no layers and fewer brush options. GIMP is more powerful and has layers, more brushes, and tools for editing photos. GIMP takes longer to learn but gives you much more control.

Do I have to pay for Krita or GIMP?

No. Both are completely free and open-source, which means anyone can use them and modify them. You can donate to support the developers if you want, but you never have to pay to use the software.

How do I make my drawing look smoother?

Use a smaller brush size and draw more slowly. You can also enable stroke smoothing in the tool options, which makes the program round out sharp corners automatically. In GIMP, this is called Smooth Stroke. In Krita, it is called Stabilization.

Can I draw text on my drawing?

Yes. Both GIMP and Krita have a text tool (usually looks like a capital A). Click the text tool, then click on your canvas where you want the text to appear, and type. You can change the font, size, and color before or after typing.
