Decode and Create JWT Tokens Online

Tool for working with JSON Web Tokens (JWT).

Decoding:

Paste a JWT token and view its parts: header, payload, and signature.

Encoding:

Create a JWT token by specifying the header, payload, and secret key. Uses HMAC-SHA256 (HS256) algorithm.

Warning: do not paste tokens with sensitive data — the tool runs in the browser, but exercise caution.
