One place for icons that do not fight each other
Most icon libraries are big. That is not the flex. The flex is consistency. If your UI mixes three stroke weights and two corner styles, users may not explain why it feels off, but they will feel it.
Icons8 Icons is built around the idea that icons should match within each style, so you can scale from a simple navigation bar to a full product without turning your interface into a collage. The library is huge, around 1.48 million free icons, which means you are far less likely to hit the point where the pack runs out and someone starts importing “close enough” SVGs from random places.
Download formats that fit real production
Icons8 supports the formats teams actually ship.
For UI and web, you can download SVG icons for crisp scaling and easy edits, or PNG icons when you need fast drop in assets for docs, slides, emails, and lightweight interfaces.
If you want motion, there is a dedicated animated collection with 4,500 plus animated icons. You can download them as GIF, Lottie JSON, or After Effects projects, which covers everything from quick prototypes to production animation pipelines.
Find the right icon fast
Searching is usually where you lose time. Icons8 adds AI search, plus search by image, so you can upload a reference and find icons that match the style instead of hunting by vague keywords.
There are also large icon packs with over 10,000 icons, which is useful when you need a consistent set for a product area like finance, travel, e commerce, or system UI.
