YAML to HTM — Private In-Browser Converter

Why convert YAML to HTM?

Converting YAML data to HTM is a shape change — the same records expressed the way the next tool in your pipeline expects to read them. HTM (HTML document) earns its place here: universally viewable structured text with live links. YAML expresses structured data with indentation rather than brackets, which is why CI pipelines, Kubernetes and app configuration live in it.

When YAML → HTM is the right move

A tool in your pipeline reads HTM but chokes on YAML.
You need to open, filter or hand the data to someone who works in HTM all day.
You are migrating configuration or exports between systems that disagree on format.

Quality, size and what changes

Records and field names carry over from YAML to HTM one-for-one. The real difference is shape: nested structures flatten when the target is tabular, and flat rows gain a wrapper when the target is hierarchical. Types are preserved where HTM has a way to express them, otherwise values become plain strings.

What you gain with HTM: Universally viewable structured text with live links.

How it works

Drop your YAML file above and Morphio decodes it locally, then re-encodes it as HTM using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

YAML to HTM — frequently asked questions

How do I convert YAML to HTM without uploading the file?

Open the YAML to HTM 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 YAML data never leaves your device and no server ever receives a copy.

Does converting YAML to HTM lose quality?

Text and structure are read locally, so nothing is retyped, re-uploaded, or sent to an OCR service. Converting YAML to HTM only rewrites the container and encoding you asked for — the source file on your disk is never modified.

Is the YAML to HTM converter free, and how big can the file be?

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.

Does converting YAML to HTM lose quality?

No. The content is remapped from YAML into HTM structurally, so nothing is re-compressed. Only features HTM has no way to express are left behind.

Can I convert several YAML files to HTM at once?

Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.

Are my YAML files uploaded anywhere?

No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
