Convert API Blueprint to Markdown.
Drop an .apib file and get clean, normalised Markdown in seconds. 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.
Already Markdown,
just tidied.
API Blueprint is written in a Markdown-based syntax already, so the conversion keeps it as-is. You get clean, normalised Markdown with no API-specific restructuring on top.
FORMAT: 1A
# My API
## GET /users
Returns all users.
# My API
## GET /users
Returns all users.
Same content, kept as clean Markdown.
Everything you
actually need.
API Blueprint in, clean Markdown out, with no server and no account anywhere.
It never leaves your browser
The .apib file is read and converted 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.
# My API
## GET /users
kept as-is
Already Markdown
API Blueprint is a Markdown-based syntax, so your headings and prose come through kept as-is.
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.
API Blueprint is already a Markdown-based format, so nothing is lost. Your text is kept as-is; the converter simply does not restructure the API on top of it.
Kept
4- Headings & sections
- Endpoint descriptions
- Code samples
- Tables and lists
Not restructured
4- No endpoint tables generated
- Schemas left inline
- Examples left inline
- No API summary built
