What is removed during minification?

All lines that are purely comments (starting with #), all blank lines, and leading/trailing whitespace on each line are removed. Inline comments at the end of a value line are also stripped.

Is the output still valid YAML?

Yes — removing comments and blank lines does not affect YAML structure. The minified output is valid and parseable by any standard YAML library.

When would I minify YAML?

Common cases include embedding a config in a shell script or environment variable, reducing file size for network transfer, or cleaning up generated YAML that contains many auto-inserted comments.

Paste YAML and remove all comments (# ...), blank lines, and unnecessary whitespace while preserving the data structure. Useful for reducing config file size before embedding in environment variables or shell scripts.
