JWT Decoder
Decode and inspect JSON Web Tokens (JWT) locally in your browser. View the header, payload, and signature securely without sending tokens to a server.
Processing happens completely locally in your browser. Tokens are never sent to a server.
Security Note: This tool only decodes the contents of the JWT. It does not verify the signature or validate the token's authenticity. Decoding a JWT locally does not prove that its contents are trustworthy.
