About this icon

Use the Block One icon

Icons in the bold style — like Block One — are designed for interface components and product UI. Use it across login and authentication flows, permission management panels, privacy settings, VPN apps, and security dashboards for a consistent, professional look.

IconStash's editor lets you fine-tune color, size, and stroke width in real time, then export in the format that fits your workflow: SVG, PNG, JSX, or CSS background-mask.

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 Block One icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Block One is the solid cut of ByteDance's IconPark set. Solid glyphs carry more visual weight than outlines, which makes them the better choice for selected states, active navigation items and small sizes where a thin stroke would otherwise disappear.

UX best practices

Security icons carry more weight than most: users read a lock, shield or key as a trust signal, so the Block One icon should never be decorative. Place it next to the mechanism it actually describes — the payment step, the HTTPS indicator, the permission toggle — rather than in a generic header where it implies protection that may not exist.

Use in your project

React / npm — IconPark Solid

npm install @icon-park/react

import { BlockOne } from '@icon-park/react';

// JSX usage:
<BlockOne theme="filled" size={24} fill="#000" />

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