Converting YAML to Markdown gives you the same content in a different container. It runs in your browser: nothing is uploaded, there is no queue and no size limit.
What changes when you convert YAML to Markdown
- Nothing in your content changes: only the container does. This is a fast, exact conversion.
When to convert, and when not to
Convert to Markdown for documentation and notes. Plain text with light formatting. The native language of README files and note apps.
Keep YAML for configuration files. Human-friendly configuration. Indentation instead of braces.
How to convert YAML to Markdown
- Drop your YAML file on the converter above, or click to choose. Several at once is fine.
- Check the options if you need them: there are none for this pair, it just works.
- Click Convert, then Download. Nothing was sent anywhere, your browser did the work.
Questions
Is my YAML file uploaded?
No. The conversion runs in your browser with WebAssembly. There is no upload endpoint on this site. You can open your browser's Network tab, or go offline after the page loads, and it still works.
Is there a file size limit?
No fixed one. The limit is your device's memory: a large data file on a phone is slower than on a laptop, but nothing is rejected for being big.
Is it free?
Yes, without an account, without a daily cap and without a watermark. Your device does the computing, so there is no server bill to pass on.
Will the quality drop?
No. Markdown is lossless: the data content is stored exactly.
Can I convert several files at once?
Yes. Drop them all; each is converted in turn and you can download them one by one or as a single ZIP.
Which engine does the conversion?
Data engine (SheetJS, js-yaml, fast-xml-parser, smol-toml), compiled to WebAssembly and running in your browser. First use downloads about 0.9 MB, cached afterwards.
