Why convert YML to YAML?

Converting YML data to YAML is a shape change — the same records expressed the way the next tool in your pipeline expects to read them. YAML (YAML Ain't Markup Language) earns its place here: human-friendly structured configuration with comments allowed. YML is YAML with the shorter extension — the same indentation-based structured data format used across DevOps tooling.

When YML → YAML is the right move

  • A tool in your pipeline reads YAML but chokes on YML.
  • You need to open, filter or hand the data to someone who works in YAML 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 YML to YAML 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 YAML has a way to express them, otherwise values become plain strings.

How it works

Drop your YML 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. Batch as many files as your machine can handle. See exactly how in-browser conversion works.

YML to YAML — frequently asked questions

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

Open the YML 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 YML data never leaves your device and no server ever receives a copy.

Does converting YML to YAML lose quality?

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

Is the YML to YAML 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 YML to YAML lose quality?

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

Can I convert several YML files to YAML 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 YML 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.
