About this icon
Use the Envelope Open icon
Icons in the outline style — like Envelope Open — are designed for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical. Use it across rich text editors, design tools, image editors, drawing apps, content creation platforms, and creative suites 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 Envelope Open icon stays pixel-perfect at 16px, 24px, 48px, and any large marketing size.
Design & UX integration
Aesthetic characteristics
Phosphor draws Envelope Open 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 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 { EnvelopeOpen } from 'phosphor-react';
// JSX usage:
<EnvelopeOpen size={24} weight="regular" />Copy the SVG markup directly from the IconStash editor to use the Envelope Open icon without any npm package — paste it into HTML, JSX, or a design tool.
