When to Use This Tool
Decode Base64-encoded Kubernetes manifests, ConfigMaps, and Secrets. Many K8s objects store configuration data as Base64, and this tool helps you inspect the actual YAML content.
Recommended: DevOps
Inspect YAML configuration files from CI/CD systems that were Base64-encoded for storage or transmission. Common in GitHub Actions, GitLab CI, and other pipeline configurations.
Recommended: Development
Decode Docker Compose files or container configurations that were encoded for secure storage. Useful for troubleshooting containerized applications and deployment configurations.

Frequently Asked Questions
What does this tool do?
This tool decodes Base64-encoded strings and displays them as YAML content. It's perfect for inspecting encoded Kubernetes configs, CI/CD pipelines, and other YAML-based configuration files.
Does this validate YAML syntax?
The tool performs basic validation to check if the decoded content looks like YAML (has colons, lists, or indentation). For full YAML validation, you can use a dedicated YAML validator after decoding.
Can I use this for Kubernetes Secrets?
Yes! Kubernetes Secrets store data as Base64-encoded strings. This tool is perfect for decoding those values to see the actual configuration data, whether it's YAML, JSON, or plain text.
Is my data safe?
Absolutely! All decoding happens entirely in your browser using client-side JavaScript. No data is ever sent to any server, ensuring complete privacy and security for your configuration files.
What if the decoded data isn't YAML?
If the decoded content isn't YAML, the tool will still display it but may show a warning. You can use Base64 to ASCII for generic text decoding if the content isn't in YAML format.
