Convert JavaScript to Markdown.
Drop a .js or .ts file and get Markdown with the source wrapped in a tagged code block. Everything runs in your browser, so the file never leaves your device.
Drag & drop your files

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.
The language
of the web.
JavaScript and TypeScript run everything from tiny scripts to full applications. When you want that code inside a README, an issue or a prompt, it belongs in a tagged code block. The converter wraps your source in one and leaves every character untouched.
function greet(name) {
return `Hello, ${name}`
}
console.log(greet('world'))
```javascript
function greet(name) {
return `Hello, ${name}`
}
console.log(greet('world'))
```
Everything you
actually need.
JavaScript and TypeScript in, a clean tagged block out, with no server and no account anywhere.
It never leaves your browser
Your .js or .ts file is read on your own device. Nothing is uploaded to any server, ever.
# Heading

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.
```javascript
const x = 2
```
Code, preserved
Your source is kept exactly as written in a fenced block tagged with the language, ready for syntax highlighting.
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.
Byte for
byte.
Honest about what comes through, and what stays put. These are the same notes the Formats list shows for JavaScript and TypeScript, so the page never drifts from what the converter really does.
Kept
2- Every line of source, byte for byte
- A fenced block tagged javascript or typescript
Preserved
2- Indentation, comments and blank lines
- Template literals, JSX and unicode
function greet(name) {
return `Hello, ${name}`
}
console.log(greet('world'))
Script questions,
answered.
Everything worth knowing before you drop in a JavaScript or TypeScript file.
