About the 404 Error Browser Window black outline icon
A rounded browser window with two dots and a long address bar in its title row, and the numerals 404 filling the page area below. It communicates a page-not-found response, a broken link or a dead URL. Useful on custom error pages, website status and uptime dashboards, SEO and crawl-report tools, hosting control panels, and empty-state screens in web apps and admin templates.
The wide window frame has generous corner radii, and the oversized digits sit centered with even spacing so the message reads from across a room. The two small circles echo browser controls. Pair it with broken link, warning, server and no-connection icons; at very small sizes drop the surrounding frame and keep only the numerals.
This is the black outline version of the 404 error browser window icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
