About the Inbox black filled icon
A closed envelope drawn as a rounded rectangle with two diagonal seams crossing at a shallow V in the middle, the classic sealed-letter view. It communicates receiving mail, messages and notifications, so it fits inbox navigation tabs, unread message badges, contact forms and footer email links, newsletter signup blocks and support ticket dashboards.
The wide landscape proportion and generous corner radius keep the shape friendly and legible, while the meeting point of the flap lines sits slightly below center for depth. Pair it with send, archive and trash icons for a complete mail toolbar, and keep the stroke aligned with neighboring interface glyphs at 24px.
This is the solid black filled version of the inbox icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
