How Designers Choose and Use Icons8 Icons, Illustrations, and 3D Assets
Icons8 is a library of icons, illustrations, and 3D assets drawn by its own designers so that styles stay consistent across formats, available for download in SVG and PNG, with an MCP server for AI agents and coding tools. It fits designers who need a matching set fast — a UI, a deck, or a landing page — and who want vector files they can still edit. It is less suited to work that requires a fully custom visual language, since ready-made assets carry the house style of whichever set you pick.
Start by matching the asset style to the project
The fastest way to waste time is to pick assets one at a time by look. Decide the style first, then filter everything to that style.
| Project type | Style that usually fits | Why |
|---|---|---|
| Product UI, dashboards, dense screens | Outline or filled icon set, one weight | Small sizes stay legible; mixing outline and filled in one toolbar reads as an error |
| Marketing pages, hero sections | Flat or 3D illustrations | More visual weight, room to carry a concept |
| Slides, internal docs | PNG icons and simple illustrations | Fast to drop in, no vector editing needed |
| Brand-critical or editorial work | Custom or heavily edited assets | Ready-made sets are recognizable and shared across many products |
The consistency claim in Icons8's own description — icons and illustrations "drawn by our own designers so every style matches" — is the practical reason to filter by one style across all three asset types rather than mixing a 3D illustration with an outline icon set.
Pick the file format by what happens next
- SVG — editable vector. Use it when the asset will be recolored, resized without loss, animated, or handed to a developer. This is the default for UI work.
- PNG — raster. Use it for quick mockups, slides, and anywhere you cannot paste or render vector files.
If you are unsure, download SVG. You can always export a PNG from it later; you cannot cleanly go the other way.
Keep a set consistent
- Choose one style (for example, a single outline weight) before searching.
- Filter icons, illustrations, and 3D to that same style so a page does not mix visual languages.
- Reuse the same icon for the same meaning across screens — a second "settings" icon in a different style is a common slip.
- Check the set covers your edge cases (empty states, errors, onboarding) before committing, not after you have built ten screens.
Check licensing and pricing before client work
Icons8 lists a pricing page, which is the place to confirm what a given use requires. Before shipping assets in client or commercial work, verify the license terms for the specific asset and plan rather than assuming downloads are unrestricted. Pricing and plan details are not covered here — check the site directly, since terms and prices change.
Getting assets into your workflow
- Figma and design tools — SVG imports as editable vector layers, so you can recolor and resize inside the file.
- Web — SVG inline or as a file keeps icons sharp at any size and lets CSS control color.
- Presentations — PNG avoids font and vector rendering issues in slide software.
Icons8 also offers an MCP server for AI agents and coding tools, which is relevant if you are wiring asset lookup into an automated or agent-driven workflow rather than browsing manually.
Customize or download ready-made?
Download ready-made when the asset is generic — a search icon, a folder, a chart — and speed matters more than uniqueness. Customize (recolor, adjust stroke, simplify) when the asset sits in a branded context or appears at large size where its original style would clash. Build fully custom only when the visual language itself is the product, since that is where a shared library stops helping.
