JWT Decoder
Decode and inspect JWT tokens to view header, payload, and signature
How to Decode JWTs
- Paste your JWT; we split header, payload, and signature.
- Header and payload are base64url‑decoded for easy reading.
- We don't verify signatures; use your server or JWKS for verification.
Security Notes
- Never paste secrets or production tokens you don't control.
- Decoding is not verification—check signature and issuer on the backend.
