Game UI Icons and Design Resources - Free Packs for Game Developers

Resources & Downloads

Working on a game development project for the first time and the icon and UI design conventions are different enough from web/brand work that I had to build a new reference library. Sharing what’s been useful.

Game UI icon conventions that differ from standard UI:

Scale and visual weight: game UI icons are typically viewed at a distance or in motion. They need strong silhouettes readable at small sizes against complex, often textured backgrounds. High contrast edges are essential.

Style cohesion: the icon set needs to match the game’s visual language, not generic UI icon conventions. A fantasy RPG, a sci-fi shooter, and a puzzle game need fundamentally different icon aesthetics even if they serve the same functions.

State communication: icons in games communicate more states than typical UI - not just active/inactive but cooldown, charge level, equipped, limited, legendary. Building state variants into the design system from the start saves significant rework.

Resources I’ve found:

Game-icons.net - large free library of SVG game icons with open licensing. Searchable by category. Good starting point and reference for visual conventions.

Kenney.nl - free game asset packs including icon sets with consistent style. Particularly good for prototype work.

itch.io asset marketplace - paid and free game UI packs from indie designers. Style range is broad, quality is variable, but the best ones are excellent.

For commissioned game UI work: establish the visual language rules (stroke weight, corner radius, gradient conventions, shadow treatment) before production. Icon sets are much faster to produce once those parameters are locked.

Anyone doing regular game UI work? Curious what the production workflow looks like for you.

Game-icons.net is the correct free resource. Large catalog, consistent SVG format, open licensing. The visual style is utilitarian but the coverage of game-specific concepts (combat, resource gathering, equipment types) means you’ll find something close to what you need for reference even if you’re illustrating your own.

The silhouette readability requirement changes how you approach game icon design versus UI icon design. In standard UI you can rely on line work and subtle detail. In game UI the icon has to read as a shape against a background that’s fighting for attention. Test in context constantly.

@zara.phantom state variant management is genuinely the hardest part of game UI icon production at scale. Building the full state matrix upfront (and getting sign-off on it before production) is the professional approach. Adding states retroactively to a large icon set is painful.

For the visual language rules document: I’d add animation conventions to that list for game UI. Icons in games often animate on state change - knowing whether something gets a scale bounce, a color pulse, or a particle effect before illustration starts affects how the base icon is designed.

itch.io for game assets is a resource I didn’t know about until recently and the range is genuinely impressive. some of the indie designers there producing game UI packs have a level of craft that rivals commercial sources. the discovery mechanism is just less good than marketplace sites.
