About the Inbox black outline icon
A wide rectangular envelope is shown flap side out, with two diagonal fold lines running from the top corners down to a shallow V at the center. It stands for incoming mail, messages and notifications. Use it for email clients, inbox and message center screens, contact and newsletter sign-up sections, support ticket queues and navigation bars.
The near 3:2 rectangle and centered fold lines make a symmetric shape that reads clearly even at 16 px, where the diagonals stay crisp on the pixel grid. Pair it with sent, archive, trash and bell icons so the mail toolbar keeps one visual weight.
This is the black outline version of the inbox 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.
