Turning a MD file into YAML changes what you can do with the document: read it, edit it, sign it, print it or hand it to a system that insists on one format. YAML (YAML Ain't Markup Language) earns its place here: human-friendly structured configuration with comments allowed. Markdown is plain text with a light sprinkle of syntax for headings, lists and links. Developers, note-takers and documentation teams write in it because it stays readable raw.

Text and structure move across from MD to YAML; how faithfully the layout follows depends on how much layout YAML can express. Fixed-layout targets keep pagination exactly as it looks, while text-oriented targets keep the words and headings and let the reader reflow them. Fonts not embedded in the source are substituted.
What you gain with YAML: Human-friendly structured configuration with comments allowed.
Drop your MD file above and Morphio decodes it locally, then re-encodes it as YAML using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Free supports batches of 5 files; Pro supports batches of 250, subject to your device's memory. See exactly how in-browser conversion works.
Open the MD to YAML page, drop your document on the drop zone and press convert. Morphio runs local parsers such as pdf.js that execute in your own tab, so the MD data never leaves your device and no server ever receives a copy.
Text and structure are read locally, so nothing is retyped, re-uploaded, or sent to an OCR service. Converting MD to YAML only rewrites the container and encoding you asked for — the source file on your disk is never modified.
Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.
No. The content is remapped from MD into YAML structurally, so nothing is re-compressed. Only features YAML has no way to express are left behind.
Yes — Free supports batches of 5 files and 10 conversions per day; Pro supports batches of 250 with no daily conversion cap. Your device's memory can impose a lower practical limit. Only usage counts reach the server, never files.
No. The conversion runs entirely inside your browser, so the file never leaves your device. The page and the required decoder must load first; free usage-limit checks may require a connection.
