JWT Decoder

Decode and inspect JWT tokens to view header, payload, and signature

How to Decode JWTs

  1. Paste your JWT; we split header, payload, and signature.
  2. Header and payload are base64url‑decoded for easy reading.
  3. 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.
