Convert SMILES to Markdown.
Drop a SMILES file and every molecular string is wrapped in a fenced code block, untouched. It runs entirely in your browser, so your file never leaves your device.
Drag & drop your files
or
Optimize for AI & RAG
Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.
Add YAML front matter
Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.
Add table of contents
Build a linked index from the headings. Handy for long documents.
Export RAG chunks (.json)
Split the result into retrieval-ready chunks. Download per file from the result panel.
Most converters quietly upload your documents to a server. This one physically can't.
Nothing changed,
nothing lost.
A SMILES string is the exact recipe for a molecule, where a single character matters. This conversion is lossless: each line is copied verbatim into a fenced code block, so the characters and their order stay intact.
CN1C=NC2=C1C(=O)N(C(=O)N2C)C
OC(=O)CC(O)(CC(=O)O)C(=O)O
```smiles
CN1C=NC2=C1C(=O)N(C(=O)N2C)C
OC(=O)CC(O)(CC(=O)O)C(=O)O
```
Everything you
actually need.
A SMILES file in, a fenced code block out, with no server and no account anywhere.
It never leaves your browser
Your .smiles is read on your device and the strings stay there. Nothing is uploaded to any server, ever.
# Heading
- point one
3 chunks
AI & RAG ready
Optional cleanup, YAML front matter, a table of contents and RAG chunk export.
Works offline
Once the page has loaded you can switch off your connection and it keeps converting.
```smiles
CN1C=NC2=C1C(=O)N(C(=O)N2C)C
```
Strings, preserved
Every SMILES line is kept verbatim inside a fenced code block, so nothing is lost.
Unicode safe
Accents, symbols and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one file or a thousand; it all runs the same way, on your own device.
What survives
the trip.
Honest about what comes through. Because SMILES is lossless, the whole file is kept and every string is preserved exactly, so the page never drifts from what the converter really does.
Kept
2- The full file content
- Wrapped in a fenced code block
Preserved
2- Every SMILES string
- Exact characters and order
```smiles
CN1C=NC2=C1C(=O)N(C(=O)N2C)C
OC(=O)CC(O)(CC(=O)O)C(=O)O
