About the JWT Decoder
This free JWT decoder reads a JSON Web Token and shows its header and payload as formatted JSON, plus human-readable dates for issued/expiry times.
Decoding happens in your browser — your token is never uploaded. (This tool decodes the token; it does not verify the signature.)
How to use it
- Paste your JWT (the xxxxx.yyyyy.zzzzz string)
- Read the decoded header and payload below
- Copy either part if you need it
