SMILES to structure viewer
Paste a SMILES string to render the 2D structure and download it as a clean SVG — instantly, in your browser.
Result
This viewer turns a SMILES string into a 2D structural drawing you can download as a scalable SVG for slides, papers, or notes. The depiction is generated locally, so it works offline and nothing is uploaded. For higher-fidelity rendering, 3D views, and verified answers, the full Cheemly workspace uses RDKit server-side.
How to draw a chemical structure from a SMILES string
- 1.Paste or type the SMILES string into the input box.
- 2.The 2D structure is drawn immediately from the parsed molecule.
- 3.Click "Download SVG" to save a scalable vector image for slides or documents.
- 4.Edit the SMILES to update the drawing in real time.
Frequently asked questions
- Can I download the structure as an image?
- Yes. The structure is rendered as an SVG, which you can download with one click and scale to any size without losing quality — ideal for presentations and publications.
- Why does my SMILES not render?
- If the SMILES string cannot be parsed — for example because of mismatched brackets or an impossible valence — no structure is drawn and the tool flags the input. Fix the syntax and the drawing updates instantly.
- Does this work offline?
- Once the page has loaded, rendering happens locally in your browser, so it continues to work without a network connection and never uploads your structure.
