UTF-8-safe Base64, processed entirely in your browser — nothing is uploaded.
Decode Base64 Kubernetes Secrets to YAML, free. Base64 to YAML decoding reverses Base64 (RFC 4648) back to text and validates the result as YAML — the quick, offline way to read a Kubernetes Secret value without exposing it to a server. Decoding runs entirely in your browser, so secret values never leave your device.
It decodes a Secret's data value back to readable YAML, restores indentation and Unicode byte-exactly, and flags when the decoded text isn't valid YAML. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Decodes the Base64 and validates the result as YAML so you can read the original config.
Paste a value from a Kubernetes Secret's data field to inspect it locally.
Indentation, block scalars and non-ASCII characters are restored exactly.
Secret values are decoded locally and never leave your browser.
Copy the Base64 string from the Secret's data field, paste it here and click Decode. The tool decodes the bytes back to text and validates the result as YAML, so you can read the original config or credential. Everything happens locally — secret values never leave your browser.
Each entry under data is encoded separately, so decode them one at a time here, or on a cluster run kubectl get secret <name> -o jsonpath. This tool is the quick, offline way to inspect a single value without exposing it to a server.
The tool flags when the decoded text does not parse as valid YAML — useful for telling apart a value that was genuinely YAML from one that was a plain string, a certificate, or binary data that merely lived in a Secret. The raw decoded text is still shown.
Yes from a privacy standpoint — decoding runs entirely in your browser with no upload or logging. Operationally, remember that Base64 is not encryption: the value was never secret to anyone who could read the manifest.
Yes. Base64 is byte-exact, so indentation, block scalars and non-ASCII characters are restored exactly; the result is then re-serialized as clean YAML.
