# Introduction to MolDraw

> MolDraw is a free chemical structure editor that runs in your browser. You can draw molecules and reactions, view them in 3D, and export figures for papers and slides.

## What you can do with MolDraw

- Draw molecules, rings and reactions on an open canvas.
- Turn a name, SMILES or CAS number into a structure.
- See the formula, weight and name of what you draw.
- Rotate your molecule in 3D.
- Export PNG, SVG, PDF, MOL, CDXML and more.
- Add plugins for NMR, ChEMBL data and more.

## Do you need an account

You do not need an account to draw. Your work saves in your browser. Sign in when you want plugins, Community posts or cloud features.
