## What is JwtDecoder?

JwtDecoder decodes any JSON Web Token in an instant and shows you exactly what is inside — header, payload, and every claim — without a single byte leaving your device.

Built for developers tired of pasting production tokens into random websites, it does the whole job locally. Paste a token and it splits out the header and payload, pretty-prints the JSON, and translates the standard claims into plain language: when the token was issued, when it expires, who it is for, and whether it is already stale.

HOW IT WORKS
Copy a JWT from your logs, terminal, or browser and paste it in — the decoded claims appear right away. Tap any claim to inspect it, and expiry and issued-at times are rendered as readable dates so you can spot an expired token at a glance. Everything runs offline: no network calls, no accounts, no tracking.

FEATURES
• Instant local decode of any JWT header and payload
• Plain-language summary of standard claims (iss, aud, exp, iat, and more)
• Readable expiry and issued-at timestamps
• Recent-token history so you can revisit what you decoded
• Clean, distraction-free single-screen flow

PRO
A single one-time unlock adds the full power-user toolkit:
• Verify HS256/384/512 signatures locally with your own secret
• Build and sign custom test tokens for your own APIs
• Batch-decode a whole list of tokens at once and export the results
• Unlimited decode history

PRIVACY
JwtDecoder works entirely on your device. Your tokens, secrets, and history never leave your iPhone — there are no servers, no analytics, and no third-party SDKs. What you decode stays yours.
