Convert Java to Markdown.
Drop a .java file and get Markdown that wraps the whole class in a fenced code block, byte for byte. It runs entirely in your browser, so your 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.
Whole classes,
intact.
Java files are verbose and class-heavy: packages, imports, annotations, generics and Javadoc all stacked together. Sharing one as plain text often loses the indentation and runs the braces together. Converting wraps the whole source in a fenced block tagged java that highlights cleanly.
class Main {
public static void main(String[] a) {
System.out.println("Hello");
}
}
```java
class Main {
public static void main(String[] a) {
System.out.println("Hello");
}
}
```
Everything you
actually need.
A .java file in, a clean fenced block out, with no server and no account anywhere.
It never leaves your browser
Your .java file is read on your own device. Nothing is uploaded to any server, ever.

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.
```java
System.out.println("hi");
```
Code, preserved
The source is kept verbatim in a fenced block tagged java, so every method, generic and annotation stays exactly as you wrote it.
Unicode safe
Accented identifiers, string literals and non-Latin scripts come through intact as UTF-8.
Free, and unlimited
No sign-up, no quotas, no watermarks. Convert one class or a whole source tree; it all runs the same way, on your own device.
Nothing is
lost.
Honest about what comes through, and what stays put for Java. These are the same notes the Formats list shows, so the page never drifts from what the converter really does.
Kept
2- Every line of source, byte for byte
- A fenced block tagged java
Preserved
2- Indentation, blank lines and braces
- Javadoc comments, annotations and unicode
class Main {
public static void main(String[] a) {

Everything worth knowing before you drop in a .java file.
