About this icon

Use the Text Underline Fill icon

This bold icon from Phosphor works well across general-purpose product UIs, design systems, component libraries, web applications, and marketing sites. The bold visual style is specifically suited for interface components and product UI.

Customize it in IconStash: pick a color preset or enter any hex code, set exact dimensions, adjust stroke weight, then copy SVG code or download a PNG — no account needed.

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 Text Underline Fill icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Phosphor draws Text Underline Fill with a uniform stroke weight and generous curves. Its defining feature is a six-weight system — Thin, Light, Regular, Bold, Fill and Duotone — so one concept can carry an entire visual hierarchy without you switching icon families mid-product.

UX best practices

As a general interface glyph, the Text Underline Fill 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 — Phosphor

npm install phosphor-react

import { TextUnderlineFill } from 'phosphor-react';

// JSX usage:
<TextUnderlineFill size={24} weight="regular" />

Copy the SVG markup directly from the IconStash editor to use the Text Underline Fill icon without any npm package — paste it into HTML, JSX, or a design tool.
