Structure to SMILES Converter
In short: Draw a molecule in the 2D editor and get the SMILES string in realtime. It is free, works in your web browser and needs no download.
Draw or edit a molecule in the 2D editor on the left. The SMILES string updates on the right as the structure changes.
Quick answer: draw a molecule in the editor and copy the realtime SMILES output.
2D Structure Editor
Loading editor...How Structure to SMILES Works
This page embeds the existing MolDraw 2D editor and listens for realtime editor messages. When the MolDraw editor updates the molecule, the tool reads the generated SMILES and displays it in the output box.
- Use it when you want to sketch a molecule and immediately copy a SMILES string.
- Check stereochemistry, charges, aromaticity, and salts before using SMILES in databases or modeling workflows.
- For the reverse workflow, use the SMILES to Structure tool.
