About this tool
Parse JWT runs entirely in your browser. Parse JWT decodes a JSON Web Token in your browser, showing the header and payload without verifying secrets remotely.
Signature verification that needs a secret should be done in a trusted environment; Parse JWT focuses on decoding. It behaves the same on desktop and mobile, with nothing stored remotely.
