About this tool
Encodes and decodes base64, base64url, base32, hex, binary, octal, URL encoding, and form encoding, all side by side, so you can see which encoding a mystery string is in.
Good for
- Decoding a base64 blob from a Kubernetes Secret, a header, or a log line
- Building a URL-encoded query string by hand
- Working out what format an opaque value is in
Not for
- Hiding anything: encoding isn't encryption, and anyone can reverse every format here
- Pasting live secrets on a shared or untrusted machine: it runs locally, but your screen and clipboard don't
