JWT Decoder
Decode JWT header and payload locally. Does not verify signatures.
Decode only — signature is not verified. Do not trust tokens without server-side verification.
How to use it
- Paste a JWT
- View decoded header and payload
- Copy JSON if needed
Features
- Header + payload view
- Local only
- No signature verify (by design)
Common questions
Does this verify the token?
No. It only decodes. Never trust a JWT without proper signature verification on a server.
