About JWT Decoder
Decode a JSON Web Token and inspect its header, payload and signature in a readable, formatted view. It shows the claims (issuer, expiry, subject) and decodes Base64URL segments without verifying the signature, so you can inspect any token safely. Useful for debugging auth flows and API tokens.
Common uses
- Inspect token claims during auth debugging
- Check token expiry and issuer
- Read the payload of an opaque token
