Four wifi signal arcs above a dot inside a circular outline
About the Signal color filled icon
Four concentric arcs rise above a small solid dot, all enclosed in a thin circular outline, the standard reading for a wireless transmission spreading outward from its source. It communicates connectivity, reception strength and network availability. Use it for wifi status indicators, router and modem setup flows, hotspot toggles in mobile settings, coverage maps in telecom presentations, and smart home device pairing screens.
The arcs step up in even increments, giving a strength ramp that survives heavy downscaling, and the surrounding circle turns it into a badge that pairs with circled bluetooth, battery and antenna marks. At 16 px, use the arcs alone without the ring.
This is the colour filled version of the signal icon: a flat, solid-colour shape that stands out in dashboards, marketing pages and app tiles where the icon needs to carry colour meaning.
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.
