JWT Decoder

Read a JWT header and payload without verifying its signature.

Signature not verified. Decoding does not establish authenticity.

How it works

Three segments identify a compact JWT. Only JSON header and payload are decoded.

Example

eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJzYW1wbGUifQ.c2FtcGxl

Limits

Check the input and selected format. Signature not verified. Decoding does not establish authenticity.

JWS: header.payload.signature; JWE: ×
