Decode Base64 payloads you wouldn’t paste into a sketchy host
Tokens and config snippets show up as Base64 all day. Paste, decode, read — locally. Invalid alphabet → clear error.
chars: 24
When to use
Peeking at non-sensitive encoded blobs or reversing an encode you just made.
Examples
How it works
Normalizes URL-safe → standard, decodes bytes → UTF-8 string (notes replacement on invalid UTF-8).
Common pitfalls
- Missing padding can fail some decoders — try adding =.
- Decoded bytes may not be UTF-8 text.
- Still not encryption.
How this differs
Opposite of Base64 Encode. JWT Decode is specialized for token segments.
FAQ
Can I decode JWTs here?
Prefer JWT Decode for three-part tokens; this is raw Base64.
Missing padding?
Auto-fix when safe.
Binary output?
Show hex/download if implemented; default UTF-8 text.
Reverse?
Base64 Encode.
