JWT Decoder
Paste a JSON Web Token (JWT) to decode and inspect its header and payload. Decoding happens entirely in your browser — the token is never transmitted. Note this tool decodes but does not verify the signature.
Header
{
"alg": "HS256",
"typ": "JWT"
}Payload
{
"sub": "1234567890",
"name": "Remoterama User",
"role": "admin",
"iat": 1700000000
}This tool decodes the token locally. It does not verify the signature.
How to use
- Paste your JWT into the input field.
- The header and payload are decoded automatically.
- Review the claims (iss, sub, exp, etc.).
- Nothing is sent anywhere — it's all local.
