How to render chemistry structural diagrams

The chemfig package provides powerful notation for drawing structural chemistry diagrams in LaTeX. FormaTeX renders your chemfig formulas as PNG, SVG, or PDF images that can be used in papers, presentations, and educational materials.

Enter your chemfig notation — such as *6(-=-=-=) for benzene — and click Render. The tool handles the full compilation pipeline including the chemfig and TikZ packages automatically.
