About this icon
Use the Envelope Open icon
The Envelope Open icon (Heroicons) is categorized under Editing. Its outline style is optimal for app navigation bars, toolbar buttons, form labels, and UI controls where clarity at 16–24px is critical and scales cleanly from 16px to 512px.
Use the IconStash detail panel to preview with a custom background, adjust stroke width, and generate production-ready SVG or PNG files without any external tools.
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
Heroicons is made by the Tailwind CSS team, and Envelope Open shows it: geometry tuned to sit on Tailwind's spacing scale and to stay legible at 16px, 20px and 24px. Every icon ships in both outline and solid, so you can change style without changing size or re-aligning anything.
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.
