Same minimal single-stroke treatment, different grid and corner style. ### Adjust stroke weight Line icons support adjustable stroke thickness in SVG, so you can match your interface's visual weight. ### Drop into your project Works in Figma, code, slide decks, or any tool that accepts SVG or PNG. ## Where simple icons work best ### Dense dashboards and tables Minimal shapes read fast in dense layouts, where filled or colored icons would add visual noise. ### Sidebar navigation and toolbars A single thin stroke stays out of the way. Simple icons annotate the interface instead of competing with it. ### Inline with body text Line weight matched to your font stays legible next to text at small sizes, without feeling heavier than the copy around it. ### Wireframes and diagrams Clean single-stroke icons work as placeholders and finished assets alike, so a diagram never needs a second pass. ## Works in your tools * [Mac App](https://home.streamlinehq.com/plugins/download): Drag and drop icons directly into any app * [Figma](https://www.figma.com/community/plugin/852192486284901337): Browse and insert icons without leaving Figma * [Framer](https://www.framer.com/marketplace/plugins/core-icons-by-streamline/): Use icons natively in Framer projects * [Webflow](https://webflow.com/apps/detail/streamline-icons): Add icons directly to Webflow sites * [VS Code](https://marketplace.visualstudio.com/items?itemName=streamline.streamline-icons): Insert icons as SVG or JSX in editors * [Lucid](https://lucid.co/marketplace/01f05f6d/streamline-icons-illustrations-emojis-and-elements): Add icons to your Lucidchart diagrams * [Miro](https://miro.com/marketplace/streamline/): Drop icons into your Miro boards * [Adobe Express](https://adobesparkpost.app.link/TR9Mb7TXFLb?addOnId=w165n33k3): Use icons in Adobe Express projects ## Unlock the full library with Pro Free sets cover thousands of icons.

That restraint keeps the icon legible at small sizes and quiet next to text, which is why line icons are the default choice for interface work. Streamline draws a Line variant for every family, all built on the same underlying grid as the family's other styles, so a simple icon today can grow into a filled or colored one later without redrawing anything. ## Five line styles, one consistent stroke Core Line is the neutral, everyday choice for interface work. Flex Line softens corners for a friendlier feel. Sharp Line keeps hard angles for a technical look. Plump Line rounds further for playful contexts, and Micro Line is purpose-built for the smallest sizes on a 10px grid. Every stroke is adjustable in SVG, so the same icon can sit thin and quiet in a dense table or thicker and bolder in a hero section, without switching sets. ## Frequently asked questions Quick answers to common questions about simple icons. ### What is a simple icon? A simple icon is a minimal, single-stroke line icon with no fill and no color. It uses the fewest shapes needed to stay recognizable, which keeps it legible at small sizes and unobtrusive next to text. ### Where can I download simple icon sets? Visit [streamlinehq.com/icons](https://www.streamlinehq.com/icons) and filter by the Line style across Core, Flex, Sharp, Plump, and Micro. Download as SVG to keep the stroke weight adjustable, or PNG for a ready-to-use image. ### Can I change the stroke weight? Yes. Line icons are exported as SVG with an editable stroke, so you can thicken or thin the line in your design tool or code to match your interface's visual weight. ### Are these simple icon sets free? Yes. Every Line set has a free tier of 200 to 998 icons as SVG and PNG, no card required. Pro unlocks the full library, from 2,000+ icons on Micro up to 5,600+ on Core, Flex, Sharp, and Plump.
