1,505 free icons with ultra-thin 1px strokes from the Phosphor icon family. Perfect for minimal, airy interfaces where you want icons to guide without dominating. Open source under MIT license, available as production-ready SVG.
Thin-stroke icons do something that heavier styles cannot: they disappear into your layout while still doing their job. The Phosphor Thin collection gives you 1,505 free icons drawn at a consistent 1px weight, creating an almost weightless feel that works beautifully in content-heavy interfaces where the text should be the star.
When thin strokes are the right call
Reading apps, documentation sites, editorial layouts, and any interface where visual density is already high. Thick icons in these contexts feel like someone is shouting in a library. Thin strokes whisper just loud enough to be useful. They are especially good for sidebar navigation, inline actions, and metadata labels where the icon supports the text rather than replacing it.
What you get
1,505 free icons covering UI essentials, arrows, media, commerce, communication, and more
Consistent 1px stroke weight across every icon
Part of the larger Phosphor icon system for style consistency
Clean SVG files with optimized paths and no unnecessary markup
Open source under the MIT license, free for personal and commercial use
Designed on a 256px grid with pixel-aligned geometry
Pairs well with heavier companions
A common pattern is using thin icons for secondary actions and a bolder weight for primary ones. You could pair this set with our Solar Bold Icons to create that kind of visual hierarchy within a single interface. The thin weight handles the quiet utility elements while bold icons mark the actions that matter most.
For a slightly heavier line weight that still feels minimal, browse our Solar Linear Icons. And if you want to customize any icon's color before downloading, use our Free SVG Color Editor to get exactly the shade you need.
Tip: Thin icons work best at 24px and above. Below that, the 1px strokes can become hard to read on non-Retina displays. For very small contexts, consider a bolder weight.
