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.

01Why

Built for machines,
not for reading.

RDF/XML wraps every fact in nested tags and long namespace URIs. Converting lifts each resource out as a heading with plain-language properties.

RDFontology.rdf

<rdf:Description rdf:about="http://example.org/alice">

<rdf:type rdf:resource="http://xmlns.com/foaf/0.1/Person"/>

<foaf:name>Alice Lee</foaf:name>

</rdf:Description>

## alice

- **type:** Person

- **name:** Alice Lee

02Features

Everything you
actually need.

RDF/XML and OWL ontologies in, readable Markdown out, with no server and no account anywhere.

It never leaves your browser

The .rdf is read and parsed on your own device. 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.

## alice

- type: Person

- name: Alice Lee

Resources become sections

Each top-level resource turns into a heading with its properties listed as bullets.

éñü

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.

03Fidelity

What the graph
keeps.

Honest about what comes through, and what doesn't. These are the same notes the Formats list shows for RDF/XML, so the page never drifts from what the converter really does.
