About the 404 Error black outline icon
Two concentric circles frame the numerals 404 with a small exclamation mark set above them, the classic shorthand for a web page that could not be found. The badge shape gives it the feel of a status stamp rather than plain text, which suits error screens, broken link warnings, site health dashboards, hosting control panels and developer documentation about HTTP responses.
The ring keeps the numerals centered and readable, and the exclamation mark adds an alert cue without a separate warning triangle. Pair it with maintenance, server and search icons from the same family. Because the digits are fine, use it at 32px or larger, or as a large illustration on an empty-state page.
This is the black outline version of the 404 error 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.
