About this YAML formatter
Format - validate - keep it readable
Format and minify YAML locally in your browser for configs, pipelines and app settings.
Useful for CI/CD files, Kubernetes manifests, Docker Compose, and copied snippets -
without uploading data.
This page uses a simplified YAML parser to stay offline and dependency-free, so some
advanced YAML features are not supported.
- Format with consistent indentation
- Minify to compact YAML for transport or storage
- Optional key sorting and safe string quoting
- Everything runs locally - no uploads
FAQ
Common questions
Do you upload my YAML anywhere?
No. Formatting runs locally in your browser. Your YAML is not sent to a
server.
Why do some YAML files fail to parse?
The parser is simplified (no external libraries). Complex YAML features
(anchors, advanced tags, some multiline cases) may not be supported.
Should I enable Quote strings?
Enable it when values might be misread (numbers, booleans, special chars). It
helps avoid accidental type changes.
Does this tool work offline?
Yes. After the first load, the page can work offline thanks to browser
caching.
