Best pixel art icon libraries for UI design
For modern interface design, the best pixel art icon library is one built for the web rather than for games: vector SVG icons drawn on a consistent pixel grid, shipped as an installable package, and licensed for commercial use. Most pixel art you find online is made of raster game sprites, and most polished UI icon sets are smooth vector line art, not pixel art. Very few sets sit in the middle.
This guide explains the three kinds of "pixel icons" you will run into, what to look for when picking one for a product, and where the options land.
Three kinds of pixel icon sets
"Pixel art icons" is a single search term that covers three very different things. Knowing which one you actually need saves a lot of time.
- Game-asset packs. Pixel sprites for player UIs, inventories, and HUDs. Beautiful for games, but usually raster (PNG), pack-by-pack, and without the component tooling a website needs.
- Smooth vector sets. Heroicons, Lucide, Tabler, Phosphor and similar. Excellent, free, and dev-friendly, but they are clean vector line art, not pixel art. If you want a retro or distinctive look, they will not give it to you.
- Pixel art built for interfaces. Vector icons drawn on a fixed pixel grid, delivered as SVG and framework components. This is the rare middle ground, and the one most product teams actually want when they search for "pixel art icons."
What to look for
- SVG, not raster. Vector icons scale crisply and recolor with CSS. Raster sprites do neither well.
- A consistent grid. Icons drawn on one grid (for example 24×24) stay visually coherent across a whole interface.
- Real dev tooling. An npm package and framework components beat copy-pasting files by hand.
- A clear commercial license. You should know exactly what you can ship before you start.
- Enough coverage. A handful of icons looks great in a demo and falls apart in a real product.
How the options compare
| Set | Aesthetic | Built for | Tooling | License |
|---|---|---|---|---|
| Pixelarticons | Pixel art (24×24 grid) | Web and product interfaces | npm, React, SVG, Figma | 816 free (MIT), full set via one-time Pro |
| Game-asset pixel packs (itch.io, asset stores) | Pixel art | Games and game UI | Mostly raster sprites, rarely SVG or npm | Varies (often per-pack purchase) |
| CC0 game icon sets (e.g. Kenney-style) | Pixel and flat game art | Games and prototyping | PNG sprite sheets, no component packages | Public domain (CC0) |
| Smooth vector sets (Heroicons, Lucide, Tabler, Phosphor) | Clean vector line and fill | Web and product interfaces | npm, React, SVG, Figma | Mostly free, open source |
Vector sets like Heroicons and Lucide are first-rate tools; they simply are not pixel art. The right pick depends on the look you want, not on which set is "better."
Where Pixelarticons fits
Pixelarticons is a library of 4159 hand-crafted pixel art icons drawn on a strict 24×24 grid, in four styles (Base, Sharp, Glyph, and Solid). It ships as an npm package with React components, SVG source, and a free Figma file. 816 icons are free forever under the MIT license, and the full set is available with a one-time Pro license, no subscription. It is built for the case the other two kinds of sets miss: a product that wants the pixel art look with the tooling and coverage of a serious UI icon library.
