That restraint keeps it legible at any size, adapts cleanly to light and dark themes, and never competes with the content it sits next to. Line is Streamline's most consistent style: the world's largest and most consistent icon library, drawn by one in-house team across every family. ## One style, four personalities Core Line is neutral and compact, built for interface work. Flex Line softens every corner for a friendlier feel. Sharp Line keeps hard angles for a bold, technical look. Plump Line goes further, chunky and rounded for playful, approachable projects. Every line set is drawn by the same team on the same underlying grid as its Solid and Duo counterparts, so switching between styles later never means rebuilding your icon system from scratch. ## Frequently asked questions Quick answers to common questions about line art icons. ### What are line art icons? Line art icons are drawn as a single outlined stroke with no fill, favoring clean, minimal shapes that stay legible at any size and adapt cleanly to light and dark themes. ### Where can I download line art icon sets?

Download as SVG to keep the stroke color editable, or PNG for a ready-to-use image. ### Are these line art icon sets free? Yes. Every line family has a free tier of 499 to 998 icons as SVG and PNG, no card required. Pro unlocks the full library of 5,369 to 5,616 icons per style. ### Which line style should I use? Core Line is the safest default for interface and product work. Flex Line suits friendlier, lifestyle-adjacent brands. Sharp Line fits bold, technical, or enterprise contexts. Plump Line works best for playful, education, or consumer-facing products. ### What is the difference between line and solid icons? Line icons are an outlined stroke with no fill. Solid icons are a filled shape with no stroke. Line generally reads as lighter and more neutral; Solid reads as bolder and more attention-grabbing. Most Streamline families offer both.
