Base64, URL, hex and JWT decoder

Encode and decode Base64, URL encoding and hex, and read JWT headers and payloads. Nothing leaves your browser.

A decoded token is not a verified token

The JWT reader shows the header and payload and translates the time claims. It does not check the signature, so never treat decoded content as trusted. Base64, URL encoding and hex convert in both directions and handle UTF-8 correctly.
