3D CONFORMER WORKFLOW

Convert SMILES to a 3D conformer in the browser

Choose ETKDG v3, ETKDG v2, or KDG to generate one 3D conformer from SMILES. Adding explicit hydrogens is recommended for all-atom geometry. This browser 3D molecule generator runs locally in single-threaded WebAssembly and supports SMILES to SDF V3000 and SMILES to PDB export workflows.
