About this icon

Use the 4k Bold Duotone icon

The 4k Bold Duotone icon (Solar Icons) is categorized under Interface. Its duotone style is optimal for feature highlight cards, onboarding illustrations, content-rich landing pages, and infographics and scales cleanly from 16px to 512px.

Use the IconStash detail panel to preview with a custom background, adjust stroke width, and generate production-ready SVG or PNG files without any external tools.

Export formats

Copy clean SVG vectors with one click, generate custom-size PNG files from 16px to 512px, export JSX/React components ready to paste into your project, or use the icon as a CSS background-mask for flexible theming.

All exports are based on the same editable vector — so the 4k Bold Duotone icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Solar renders 4k Bold Duotone across six styles — Linear, Outline, Bold, Duotone, Broken and Bold Duotone. Broken and Duotone are the distinctive ones: they add a deliberate gap or a second colour layer, which is what makes the set popular for SaaS dashboards and mobile apps that need hierarchy without extra colour.

UX best practices

As a general interface glyph, the 4k Bold Duotone icon does its job best between 16px and 24px, sitting next to a text label. Icon-only treatments work for a small set of universally understood actions, but comprehension falls off quickly once the action is specific to your product — so when in doubt, add the word.

Use in your project

React / npm — Solar Icons

npm install solar-icon-set

import 4kBoldDuotone from 'solar-icon-set/4kBoldDuotone';

// JSX usage:
<4kBoldDuotone size={24} iconStyle="Linear" />

Copy the SVG markup directly from the IconStash editor to use the 4k Bold Duotone icon without any npm package — paste it into HTML, JSX, or a design tool.
