A free browser-based tool that lets you open, view, edit, and validate YAML files with a live JSON preview.

How do I view YAML files online?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format commonly used for configuration files (Docker, Kubernetes, GitHub Actions, etc.).

Are my files uploaded to your servers?

No. All processing happens locally in your browser.

Is the YAML Viewer free?

Yes. Completely free with no registration required.

Is there a file size limit?

There is no fixed file size limit. Since all processing happens directly in your browser, the maximum file size depends on your device's available memory and browser capabilities. Most modern devices handle large files without any issues.
