Pixel art in one sentence
Pixel art is a digital art form in which images are built up one square at a time on a grid, with every pixel placed deliberately.
The name comes from "pix" (pictures) + "el" (element) - a pixel is the smallest element of a digital image. What makes pixel art special is that the artist works on that grid, like a mosaic, rather than drawing smooth strokes and letting software handle the details. Early games had no choice: screens had so few pixels that every single one had to count. Today, choosing to work that way is exactly the point.
What makes art "pixel art"
A fixed grid
Art is created on a small canvas like 16x16 or 32x32. The resolution is a choice, and it defines how chunky or detailed the result is.
Limited colors
Classic pixel art uses a small, intentional palette. Retro machines had strict color budgets (the Game Boy had just four shades), and many modern artists keep the same discipline.
Hard edges
No anti-aliasing or blur between colors. Shading and texture come from manual techniques like dithering - pattern of alternating pixels - rather than smooth gradients.
Scaling by integers
To display big, sprites are multiplied by whole numbers (2x, 3x, 4x) with nearest-neighbor scaling, keeping the pixels crisp squares instead of blurring them.
Is pixel art 2D, 8-bit and retro?
2D? Yes. Pixel art is inherently flat and 2D. The 3D equivalent - building with cubes instead of squares - is called voxel art (MagicaVoxel, Qubicle).
8-bit? Only some of it. "8-bit" refers to the NES / Game Boy generation (early 1980s). Pixel art also covers the 16-bit SNES / Genesis era, the Game Boy Advance, and modern indie styles that mix all of them.
Retro? In style, yes - the aesthetic is strongly tied to retro games. But it is far from dead: Celeste, Stardew Valley, Undertale and countless other modern games use pixel art every year. What you're seeing is a deliberate, nostalgic style, not an old technology.
Vector? No. Pixel art is raster (grid-based). Converting it to vector shapes makes it scalable forever, but it stops being pixel art.
A very short history of pixel art
The word "pixel" was first published in 1965 by Frederic Billingsley at NASA's Jet Propulsion Laboratory, describing the picture elements of scanned space-probe images. The term "pixel art" appeared later, in a 1982 journal letter by Adele Goldberg and Robert Flegal at Xerox PARC.
As an art form, pixel art grew from the golden age of arcade games: Space Invaders (1978), Pac-Man (1980), and the 8-bit consoles that followed - the NES (1983) and Master System (1985). Programmers of that era were often the artists too, working within tiny resolutions and tiny color budgets.
In the late 1980s and early 1990s the European demoscene turned pixel art into an art form for its own sake, with "graphicians" producing stills and animations on Commodore 64s, Atari STs and Amigas. Software like Deluxe Paint (1985) made placing pixels practical and even pleasant.
After 3D graphics took over mainstream gaming, pixel art never disappeared - it became a beloved, deliberate style. The indie game boom (Super Meat Boy, Cave Story, then Undertale, Celeste, Stardew Valley) made it one of the most visible art styles in games today.
Why pixel art "looked better" on a CRT
Old games were designed for cathode-ray tube (CRT) televisions, which did three things a modern LCD doesn't:
- •Blended the pixels - the phosphors glowed and bled into each other, softening harsh 1px steps.
- •Added scanlines - horizontal gaps between lines gave art texture and hid dithering artifacts.
- •Stretched the aspect ratio - non-square pixels made 256x240 render as a proper 4:3 image.
On a modern display, pixel art needs integer scaling (whole-number multiples, never fractions) so squares stay square and edges stay sharp. Emulators like RetroArch and mGBA have an "integer scale" option for exactly this reason. Some players add scanline shaders to recreate the CRT feel.
Famous pixel art games
- Undertale (2015) - Toby Fox's retro-style RPG; renders at 640x480 with sprites designed for crisp 2x scaling.
- Stardew Valley (2016) - the farming sim's entire world is hand-made pixel art.
- Celeste (2018) - a modern pixel platformer with a famously clean, readable style.
- Shovel Knight (2014) - intentionally follows NES-era rules of resolution and color.
- Minecraft (2011) - block-based; players also build pixel art from blocks in-game.
