Convert OPML to Markdown.
Turn an OPML outline or feed export into a tidy, nested Markdown list. The whole tree comes through, and the work happens 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.
An outline,
not a page.
OPML wraps your subscriptions inside nested tags that few apps read. Converting keeps every branch of the tree intact and writes it as an indented Markdown list with live links.
<opml><head><title>My subscriptions</title></head>
<body>
<outline text="News">
<outline text="Example Blog" xmlUrl="https://example.com/feed"/>
</outline>
</body></opml>
# My subscriptions
- News
- [Example Blog](https://example.com/feed)
Everything you
actually need.
Outlines in, a nested Markdown list out, with no server and no account anywhere.
It never leaves your browser
Your .opml is read and parsed on your 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.

Outline becomes a nested list
The title plus the full tree become indented bullets, each item linked to its URL.
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.
The whole tree
comes through.
OPML maps cleanly onto a Markdown list, so this conversion is lossless. Every level of nesting and each item link are preserved, exactly as the Formats list describes.
Kept
2- The outline title
- The full nested outline tree as an indented list
Preserved
2- Every nesting level
- Each item linked to its URL
