How to Use:

  • Paste a Base64 string into the input box or import a .txt, .yaml, or .yml file
  • The output will update automatically, showing the decoded YAML text
  • Click “Copy Output” to copy it to your clipboard
  • Click “Export to File” to download the decoded YAML
  • Use “Clear All” to reset everything
  • Enable the Maximize output toggle to expand the output area for easier viewing

What Base64-decode YAML can do:

It takes Base64-encoded text that represents a YAML structure and cleanly decodes it into readable YAML without you needing a terminal or any tools. It handles plain-text YAML safely and quickly, fully in-browser. You can paste data or import from a local file, and the tool updates in real-time. The maximize output toggle is useful when you’re working with larger YAML files and want to view the entire result without scrolling in a small box.

Example:

Input (Base64):

LS0tCmZvbzogYmFyCmJheiA6IDEyMwpzb21ldGhpbmcgOiB0ZXN0Cg==

Output (Decoded YAML):

---
foo: bar
baz : 123
something : test

Common Use Cases:

If you’ve got Base64 blobs from an API, config dump, or encoded YAML logs, this tool makes it painless to unpack them. It’s especially helpful when working with embedded config formats or debugging YAML inside encoded payloads. You just paste and go and it even counts the total characters to give you a sense of length.

Useful Tools & Suggestions:

After decoding, it’s smart to Validate YAML to make sure the structure survived the trip. And if the result looks messy or hard to follow, Prettify YAML makes it a lot easier to work with.
