How it works
- 1Paste one SMILES per line. Standard .smi lines such as “CCO ethanol” are supported.
- 2Run the conversion locally.
- 3Download one result, a combined file, or all results as ZIP.

SDF to PDB Converter
Convert single or multi-record SDF files to PDB locally without changing the stored coordinates.
✓ Single and bulk conversion✓ Runs locally in your browser✓ Combined output and ZIP download
Input
Single + BulkChoose one or more files
PDB is less expressive than SDF for bond order and properties. SDF coordinates are preserved, but SDF data fields and detailed bond semantics are not carried into PDB.
Molecular data are processed locally in your browser.

Frequently asked questions
Are my molecular files uploaded?
No. Conversion runs locally in your browser. The SMILES 3D engine code is loaded as a browser dependency, but your molecular input is not sent to Toolardo.
Does conversion preserve every property from the source format?
PDB is less expressive than SDF for bond order and properties. SDF coordinates are preserved, but SDF data fields and detailed bond semantics are not carried into PDB.
