JWT 调试器

本地解码 JWT 载荷 (不验证签名)

未验证签名

此解码器仅读取 payload claims。不验证 JWT 签名。解码后的 payload 只显示 token 的声明,不代表其真实性 — 没有服务器端签名验证,切勿信任。

使用方法

Paste a JWT — the three dot-separated segments (header, payload, signature) are split automatically.
The Base64URL header and payload are decoded into readable JSON.
Registered claims such as exp, iat, and nbf are rendered as human-readable dates next to their raw epoch values.
Decoding happens entirely in your browser; the signature is not verified and the token never leaves your machine.

示例

Paste a token like eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMjMiLCJleHAiOjE3MDAwMDAwMDB9.abc and the payload reveals sub: 123 and exp: 1700000000, shown as a readable UTC date.
If the exp claim is in the past, the tool flags the token as expired so you can spot stale credentials at a glance.
