Ready when you are

Paste a token above — or pick a sample — and it is decoded here, on your machine.

• Signed JWT (JWS) — header.payload.signature, 3 segments
• Unsecured JWT — 2 segments, alg none
• Encrypted JWT (JWE) — 5 segments; the header still decodes
• Bare base64 — any blob: JSON → text → hex, stated clearly

No installs, no accounts, no uploads. Open the page source: there is nowhere for a token to go.
