20 Best Icon Websites in 2025

Have you ever found yourself in this situation: the UI is almost finalized, but you're stuck on icons? Or you're building a small component and getting pushed for progress before you've even found the SVG? Icons might seem like small details, but choosing the wrong style can make an entire page look cheap. Honestly, I often find myself searching for icons in the gap between "wanting simplicity" and "needing personality."

This article gives you a curated list of 20 icon websites, divided into two categories: "Search/Aggregation" and "Icon Libraries/Resources." You'll find both quick entry points for finding icons and high-quality libraries worth bookmarking long-term. Whether you're building product prototypes, mobile UIs, or frontend component libraries, these sites can help you nail down a complete icon style in under 10 minutes.

How to Choose the Right Icon Website?

If you're just temporarily looking for one or two icons, prioritize "search/aggregation" sites—they're efficient and can deliver results in 3-5 minutes. If you're building a long-term product or design system, it's recommended to bookmark resource library sites for easier consistency maintenance. Simply put, the former is for "emergencies," the latter is for "long-term stability."

Additionally, when selecting icons, it's best to fix 2-3 size standards (like 16/24/32px) so that subsequent icon changes won't affect layout. One more thing: don't forget to check licensing, especially for commercial projects. It's better to spend a few minutes confirming than to hit a snag later.

Conclusion

Honestly, icons are small elements, but doing them well can elevate a product's "premium feel" by a whole level. The 20 websites above basically cover 90% of daily design and development needs: from quick searches to systematic icon libraries. You can freely combine them based on project pace and style requirements, or even create a "frequently used icon library" list in advance.

If you're pressed for time, start with efficiency-focused sites like Iconfinder, Flaticon, and Iconfont. If you're building systems or component libraries, Remix Icon, Tabler Icons, and Streamline will be more suitable. Bookmark them, and you won't panic the next time you need to find icons.
