Frequently Asked Questions

Lucide is modern and lightweight with consistent 24px line icons. Heroicons integrates seamlessly with Tailwind CSS and ships outline plus solid variants. Tabler offers the largest icon count. Carbon is ideal for enterprise apps. Choose based on your design system and style preference.

Outline (or line/stroke) icons use open paths with a consistent stroke width, giving a lightweight, modern look suited for minimalist interfaces. Filled (or solid) icons use closed shapes with a solid fill, providing higher contrast and better visibility at small sizes. Most packs in this collection — including Heroicons, Remix Icons, and Bootstrap Icons — offer both styles.

Yes. The dedicated Animated collection includes loading spinners, pulse effects, and motion icons from packs like SVG Spinners. Several UI packs such as Lucide and Tabler also support CSS and JS animation because their clean SVG structure makes keyframe and transition animations straightforward to add.

Yes. Solar Icons and Phosphor Icons in this collection include native duotone variants — icons that use two tones of a single colour for added depth. Duotone icons work especially well in dashboards and feature lists where you want visual hierarchy without introducing a second accent colour.

Every pack in this collection is released under an open-source licence (MIT, Apache 2.0, or ISC). You can use them in personal and commercial projects — websites, SaaS products, mobile apps — without attribution in most cases, though checking each pack licence page is recommended.
