Line flame with a curved outer tongue and a smaller flame shape burning inside it
About the Flame black outline icon
A tall, tapering flame drawn as one continuous curve, with a second smaller tongue of fire rising inside it and a low flicker at the base. The pairing of outer and inner flame reads instantly as heat, combustion and released energy. Useful for heat or temperature settings in appliance interfaces, calorie-burn counters in fitness apps, gas and boiler service pages, hazard labels on packaging and campfire markers on trail maps.
The silhouette is asymmetric: the outer flame leans right at the tip while the inner tongue stays upright, so the shape keeps motion even when static. Uniform stroke weight lets it sit beside drop, leaf and lightning bolt icons in an energy set. At 16 px, drop the inner flicker or use the filled style so the interior does not close up.
This is the black outline version of the flame 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.
