About this icon

Use the Envelope Simple Open icon

This outline icon from Phosphor works well across rich text editors, design tools, image editors, drawing apps, content creation platforms, and creative suites. The outline visual style is specifically suited for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical.

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

Design & UX integration

Aesthetic characteristics

Phosphor draws Envelope Simple 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 Simple 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 { EnvelopeSimpleOpen } from 'phosphor-react';

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

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