Outline IconsGenerate a matching set with AI
Outline icons describe objects by their contour: closed shapes, uniform borders, and empty interiors. Compared to freer line icons, outline icons feel slightly more solid and object-like, because each glyph reads as a bounded silhouette rather than a gesture.
When to use outline icons
Reach for outline icons when you want a neutral, professional look that stays out of the way — marketing sites, B2B products, and feature grids all benefit. They also make an excellent inactive state in tab bars, paired with a filled version of the same glyph for the active state. Generating both variants from the same prompt keeps the silhouettes aligned.

Frequently asked questions
What is the difference between outline icons and line icons?+
The terms overlap, but outline icons emphasize closed contours around whole objects, while line icons allow open strokes and floating details. Outline sets tend to look more uniform and geometric; line sets can feel lighter and more hand-crafted.
Can I generate matching filled versions of my outline icons?+
Yes. Generate your outline set, then run the same item list with the Filled style — or open a project and use style-matched expansion. Because both runs share the prompt and reference, the silhouettes stay compatible for active/inactive state pairs.
