About the Thought Bubble black outline icon

A bumpy, cloud-shaped thought bubble sits inside a thin circular frame, with two small dots trailing toward the lower left to show the thought rising from a character. It reads instantly as thinking, imagination or an unspoken idea, which makes it useful for chat and comment threads, brainstorming boards, quiz and hint buttons, onboarding tips, and slide decks about creative process.

Five overlapping lobes give the cloud an irregular, hand-drawn contour, and the two dots taper for a natural tail. Line weight matches the circular badge, so it sits well beside speech bubble, lightbulb and brain icons. Keep it at 24 px or larger so the small dots stay visible.

This is the black outline version of the thought bubble 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.
