Open Envelope black outline icon

About the Open Envelope black outline icon

An envelope stands upright with its wide triangular flap folded fully open and tipped backward, while two diagonal creases meet in the middle to show the front pocket. Nothing has been pulled out, so it reads as a message just opened and read. Suits email client inboxes, read-receipt states, newsletter signup blocks, contact sections and invitation or announcement graphics.

The composition is built from clean straight lines and two large triangles, with the open flap taking up the upper half and the body squared off below. It pairs directly with the closed envelope, mail send and inbox icons in the same set for read and unread states. Keep line weight consistent so the fold creases do not visually merge.

This is the black outline version of the open envelope icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
