About the Book Question Mark black outline icon

An open book sits inside a thin circle, its left page ruled with curved text lines while the right page carries a bold question mark. It signals questions, research and learning support rather than plain reading. Use it for FAQ and help center entry points, knowledge base articles, quiz and study apps, tutorial sections and library search screens.

Curved page edges and a visible spine give the book depth, and the question mark is sized to fill most of the right page so the meaning survives scaling. It pairs with lightbulb, graduation cap and search icons. The circular frame matches other badged icons in the set.

This is the black outline version of the book question mark 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.
