devcrate / Encoding / JWT Decoder
Encoding
Decode a JWT without sending it anywhere.
Paste a JWT to see its decoded header and payload claims. This does not verify the signature — it's for inspecting claims during development, not for trusting a token's authenticity.

How to use the jwt decoder
- Paste a JWT (three dot-separated Base64URL sections).
- Click Decode to see the header and payload as readable JSON.
- Note: this tool does not verify the signature — never trust a decoded token's contents without server-side verification.
