Your input stays local.
The toolbox is built to process developer data in the browser whenever the feature allows it.
Local processing
JSON, JWT, Base64, URL, timestamp, UUID, comparison, conversion, and generation features are designed to run locally. Do not paste secrets into any website unless you understand its processing model.
JWTs
JWT decoding reads the token locally. Decoding does not verify the signature, and tokens are never sent anywhere automatically.
