About this converter
YAML and Java Properties solve overlapping problems with different syntax. This tool converts between them in your browser using battle-tested parsers and serializers — no server round-trip, no rate limits.
How it works
- Parse the YAML into an intermediate JavaScript object.
- Normalize primitive types (numbers, booleans) where the target format supports them.
- Emit Properties using a deterministic serializer.
Privacy
- Everything runs client-side — your data never leaves the browser.
- No accounts, no tracking of input, no rate limits.
- Works offline after the first load.
