What you need to draw on a computer

Drawing on a computer requires three things: software that lets you create images, a way to input your drawing (mouse, trackpad, or pen tablet), and basic knowledge of how that software works. You do not need expensive equipment — many people start with a mouse and free software, then upgrade later if they want to.

The software you choose depends on what you want to draw. Painting and illustration programs like Krita, GIMP, and Clip Studio Paint let you use brushes, layers, and color tools. Design programs like Inkscape create shapes and text. Photo editors like Photoshop can also function as drawing tools. Each one has a different interface and a different set of features, so the right choice depends on whether you want to paint freehand, design graphics, or edit photographs.

Your input device matters less than you might think at first. A mouse works for drawing, though it is slower and less natural than a pen tablet. A trackpad on a laptop is harder to use but possible. A pen tablet — a flat device you connect to your computer and draw on with a stylus — costs between $30 and $200 and makes drawing much faster and more accurate. A pen display, which is a tablet with a screen built in, costs more but lets you draw directly on the image you are creating.

Key Takeaways

  • Free software like Krita and GIMP can do professional-quality drawing without any cost, though they have a learning curve.
  • A mouse or trackpad works for drawing, but a pen tablet under $100 makes the process much faster and more comfortable.
  • Layers let you draw different parts of an image separately and change them without affecting the rest — this is the single most useful feature in drawing software.
  • Brush settings, opacity, and blend modes control how your strokes look; learning these three things will improve your drawings when ready.
  • Most drawing software saves in its own format first; you need to export to PNG, JPG, or another format if you want to share or print your work.

Free drawing software that works well

Krita is a free, open-source painting program designed for digital artists. It has a full set of brushes, layer support, and tools for both painting and illustration. The interface is organized around the canvas in the center, with tool options on the left and layers on the right. Krita runs on Windows, Mac, and Linux. It saves in its native .kra format but exports to PNG, JPG, and other formats.

GIMP (GNU Image Manipulation Program) is older and more general-purpose than Krita — it is part photo editor, part painting tool, part design software. It has everything you need to draw, but the interface is more cluttered and the learning curve is steeper. GIMP is free and runs on all major operating systems. Many people use it for photo editing rather than drawing from scratch, but it works for both.

Clip Studio Paint has a free version with most features intact, though the paid version ($50 to $80 per year) adds more brushes and cloud storage. It is built specifically for comic and manga artists, so it has tools for panel layouts, speech bubbles, and screentone effects. The free version is genuinely usable; you are not forced to upgrade to do real work.

Photoshop costs $20 per month through Adobe's subscription. It is the industry standard for professional work, but it is overkill for learning to draw. If you already use Photoshop for other work, you can draw in it, but do not buy it just for drawing.

Setting up your first drawing workspace

Open your chosen software and create a new document. You will see a dialog asking for width, height, and resolution. For screen viewing, 1920 × 1080 pixels at 72 DPI (dots per inch) is standard. For printing, use 300 DPI and measure in inches — an 8 × 10 inch print at 300 DPI is 2400 × 3000 pixels. Start with a screen-sized image if you are learning; you can always make a larger one later.

Once your canvas is open, look for the brush tool in the toolbar. In Krita and GIMP, it is usually a paintbrush icon on the left side. Click it, then look for brush presets — these are saved brush shapes and settings. Start with a basic round brush. Set the brush size to something medium (around 20 to 50 pixels) and the opacity to 100 percent. Opacity controls how transparent your stroke is; 100 percent means fully opaque, 50 percent means semi-transparent.

Before you start drawing, create a new layer. Layers are separate surfaces you can draw on without affecting the background. In Krita, go to Layer > New Layer. In GIMP, go to Layer > New Layer. Layers are the reason digital drawing is so much more forgiving than paper — you can erase, hide, or delete a whole layer without touching anything else. Most professional drawings use 5 to 20 layers, each for a different part of the image.

Basic drawing techniques and brush control

Start by drawing straightforward shapes — circles, lines, and curves — to get used to how your input device feels. If you are using a mouse, you will notice that straight lines are hard and curves feel jerky. This is normal. A pen tablet fixes this problem almost when ready because the stylus moves the way your hand moves, not the way a mouse pointer jumps.

Brush size and opacity are your two most important controls. Larger brushes cover more area with each stroke; smaller brushes let you add detail. Opacity controls how much your stroke covers what is underneath. A stroke at 100 percent opacity completely covers the layer below. A stroke at 50 percent opacity blends with what is underneath. Many artists use low opacity (30 to 50 percent) for shading and blending, and higher opacity (80 to 100 percent) for outlines and solid shapes.

Blend modes change how your brush interacts with the layer below. The default mode is "Normal," which just paints on top. "Multiply" darkens everything underneath — useful for shadows. "Screen" lightens everything underneath — useful for highlights. "Overlay" both darkens and lightens depending on the color — useful for adding depth. You do not need to learn all of them at once; start with Normal and Multiply, then explore others as you get comfortable.

Undo is your friend. Press Ctrl+Z (Windows) or Cmd+Z (Mac) to undo your last stroke. Most software lets you undo 20 to 100 steps, so you can go back several strokes if you make a mistake. Some software also has a History panel that shows every action you have taken; you can click on any point in the history to go back to that moment.

Choosing a pen tablet if you decide to upgrade

A pen tablet sits on your desk and connects to your computer via USB or wireless. You draw on the tablet surface with a stylus, and the cursor moves on your screen. This takes a few minutes to get used to — your hand is not on the screen, so there is a disconnect — but most people adjust quickly.

Entry-level tablets like the Wacom One ($80) and Huion Pen Tablet ($50 to $70) work well for learning. They have pressure sensitivity, which means the stylus detects how hard you are pressing and adjusts the brush size or opacity accordingly. This is the single feature that makes a tablet feel natural — pressing harder makes a thicker line, just like a real pen.

Mid-range tablets like the Wacom Intuos ($80 to $100) and Huion Inspiroy ($100 to $150) add more pressure levels and larger work surfaces. A larger surface gives you more room to move your hand, which some people find more comfortable. More pressure levels (8192 versus 4096) make the stylus feel more responsive, but the difference is subtle for beginners.

Pen displays like the Wacom One Display ($430) and Huion Pen Display ($300 to $400) have a screen built in, so you draw directly on the image. These are more expensive but feel more natural because your hand is on the screen. If you are serious about drawing, a pen display is worth the cost, but start with a regular tablet to see if you like digital drawing first.

Saving and exporting your work

Drawing software saves in its own format by default. Krita saves as .kra files, GIMP saves as .xcf files, and Photoshop saves as .psd files. These formats preserve all your layers, so you can open the file later and edit individual layers. Always save your work in the native format as you go — this is your working file.

When you are done and want to share or print your drawing, you need to export it to a standard format. Go to File > Export As (or Export in some programs). Choose PNG if you want a transparent background and high quality — PNG is best for sharing online. Choose JPG if you want a smaller file size and do not need transparency — JPG is best for photos and complex images. Choose TIFF if you are printing professionally.

Before you export, flatten the image if you do not need the layers anymore. Flattening merges all layers into one, which makes the file smaller. In Krita, go to Image > Flatten Image. In GIMP, go to Image > Flatten Image. You cannot undo this, so save your layered version first, then flatten a copy.

Common mistakes and how to avoid them

Drawing with a mouse is frustrating because the cursor jumps instead of flowing. If you are struggling with a mouse, a $50 pen tablet will feel like a huge upgrade. Do not spend weeks fighting with a mouse when a tablet costs less than a restaurant meal.

Using only one layer makes it hard to fix mistakes. If you draw the whole image on one layer and make a mistake in the middle, you have to erase and redraw. With separate layers for outlines, colors, and shading, you can fix one part without touching the rest. Start with at least three layers: one for rough sketches, one for outlines, and one for color.

Saving only in the native format means you cannot share your work without exporting first. Export a copy as PNG or JPG as soon as you finish, so you have a version ready to share. Keep the native format file for editing later.

Ignoring brush settings means you are using the same brush for everything. Spend 10 minutes exploring the brush panel — change the size, opacity, and blend mode. A single brush with different settings can do the work of five brushes.

Frequently Asked Questions

Can I draw on a computer with just a mouse?

Yes, but it is slower and less natural than a pen tablet or trackpad. Many people start with a mouse and upgrade later. If you want to draw seriously, a pen tablet under $100 will make a huge difference in speed and comfort.

What is the difference between a pen tablet and a pen display?

A pen tablet is a flat surface you draw on while looking at your screen — your hand is not on the screen. A pen display has a screen built in, so you draw directly on the image. Pen displays cost more but feel more natural. Start with a pen tablet to learn; upgrade to a pen display later if you want.

Do I have to pay for drawing software?

No. Krita, GIMP, and Clip Studio Paint (free version) are all free and professional-quality. Photoshop costs $20 per month. You can learn to draw and create finished work with free software.

What resolution should I use for my drawing?

For screen viewing, 1920 × 1080 at 72 DPI is standard. For printing, use 300 DPI and measure in inches — an 8 × 10 inch print is 2400 × 3000 pixels. Start with screen size if you are learning; you can always make a larger file later.

Why does my drawing look pixelated when I zoom in?

You are probably zoomed in too far or your brush is too small. Zoom out to see the whole image, or increase your brush size. If the image itself is low resolution (under 1000 pixels wide), make a new document at higher resolution and start over.
