Serialize a parsed document with compact flow collections for a smaller transport or fixture representation while preserving its data model.
Inputs are limited to 1 MiB and stay in this browser tab.
Nothing is placed in a URL, account, preset, or remote log.
Strict, bounded, local processing
YAML minification is normalized compact serialization, not gzip compression. The result favors size over hand editing and should remain a generated artifact.
Block mappings and sequences depend on indentation and line structure. Flow-style braces and brackets allow the same parsed collections to be serialized more compactly without treating whitespace inside scalar values as formatting.
The operation parses before writing and reports output bytes. It does not promise the size savings of HTTP or archive compression, which operate across repeated content.
Dense flow output obscures nested configuration and creates noisy diffs. Keep readable source in version control and create compact YAML only when a receiving system or bounded fixture specifically benefits from it.
