- Open in browser: https://pockettoolbox.org/en/jwt-decoder
- Runs entirely in your browser; files and input are never uploaded.

## How it works

Decodes JSON Web Tokens for analysis.

Paste your JWT into the input field to decode and inspect the header, payload, and signature.

Splits the three-part token string at dot delimiters. Decodes header and payload from Base64URL into readable JSON objects, converting timestamps like expiry dates.
