The YAML Minifier strips comments, blank lines, and trailing whitespace from a YAML file to shrink it, while preserving the indentation that YAML relies on to define its structure. Paste your config or data file and get back a more compact version that still parses to the same values — unlike JSON or XML, YAML can't be collapsed to a single line, since indentation itself carries meaning. It runs entirely in your browser.
