It encodes the raw text byte-for-byte (UTF-8), not the parsed structure — decode the Base64 to recover the original YAML, not a canonical form.
How it differs from related tools
The Base64 to YAML decoder reverses this; YAML URL encoder produces percent-encoding instead of Base64.
Frequently asked questions
When is YAML Base64 encoding useful?
When you need to embed YAML as a single portable string, e.g. in env vars.
Is it private?
Yes. Encoding runs entirely in your browser.
Is the encoding reversible?
Yes. Paste the result into our Base64 to YAML decoder to get the original YAML back.
Does it compress my YAML?
No. Base64 only re-encodes the bytes; the encoded string is actually longer than the original.
