How this tool works

The transformation runs locally in your browser. Entered values are not sent to Rabetly, put in the URL, or added to analytics.

JWT header and payload sections are decoded locally as untrusted JSON. The signature is never verified and no authorization judgment is made.

Developer tools FAQ

Is my technical input uploaded?

No. These transformations run in your browser. Rabetly does not receive the JSON, source, token, header, or other value you enter.

Which browser APIs are used?

Standard browser APIs handle text conversion, secure randomness, UUIDs, timestamps, and Web Crypto hashes. No external processing API is used.

Does a decoded or formatted value run as code?

No. Results are shown as text. This category does not execute code, make network requests, verify JWT signatures, or scan external systems.
