About this icon

Use the Envelope Open Thin icon

The Envelope Open Thin icon from Phosphor fits naturally in rich text editors, design tools, image editors, drawing apps, content creation platforms, and creative suites. Its thin style makes it ideal for editorial layouts, hero sections, premium marketing pages, and large-format typographic contexts.

Open it in IconStash to set stroke color via presets or a custom hex value, choose an exact pixel size (16–512px), control stroke width (0.1–3px), and preview against dark, light, or checkered backgrounds before downloading.

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 Envelope Open Thin icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.

Design & UX integration

Aesthetic characteristics

Phosphor draws Envelope Open Thin 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

In editors and design tools, the Envelope Open Thin icon belongs in a toolbar where it can carry a tooltip and a keyboard-shortcut hint. Keep editing affordances visually lighter than the content they act on; when the chrome competes with the canvas, users lose track of their own work.

Use in your project

React / npm — Phosphor

npm install phosphor-react

import { EnvelopeOpenThin } from 'phosphor-react';

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

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