Developer Utility
JWT Decoder
Paste any JWT token to decode and inspect its three parts: header (algorithm, type), payload (claims, user data, expiration), and signature. The tool auto-detects Bearer tokens, checks expiration with visual warnings, and formats both parts as readable JSON. 100% browser-based — your tokens never leave your computer.
