Phosphor Bold Icons
1,512 icon elements1,512 free icons from the Phosphor family in the bold weight. Thicker strokes that demand attention and improve readability in low-contrast environments, on outdoor screens, and for users who benefit from higher visual weight. MIT licensed SVGs.
The Phosphor icon family gives you six weights of the same 1,512 icons. The bold weight is your tool for emphasis. Thicker strokes create higher contrast ratios, better legibility at smaller sizes, and a visual confidence that lighter weights can't match.
When to reach for bold
Bold isn't just "bigger lines." It's a design decision with practical consequences. These icons maintain full legibility on projector screens in well-lit conference rooms. They stay readable when rendered as small tab bar icons on budget Android devices. They pass WCAG contrast requirements with room to spare. Bold is the pragmatic choice when your design needs to work in imperfect conditions.

Mix weights for visual hierarchy
One of Phosphor's best features is weight mixing. Use bold for primary navigation icons that need to anchor the page. Drop to Phosphor Regular for secondary actions. Use Phosphor Light for tertiary elements. Every icon keeps its exact shape across weights, so the visual system stays perfectly coherent.
This weight-based hierarchy approach gives you design flexibility that most icon sets simply can't offer. Instead of using size or color to differentiate importance, you can use stroke weight, which preserves your color palette and layout spacing.
