TorixPulse Free Tools / JWT Decoder
JWT Decoder
Decode and inspect JSON Web Tokens. Fast, private and free — everything runs in your browser.
This decodes the token only — it does not verify the signature. Never paste production secrets or tokens you don't own.
Decode a JSON Web Token
A JWT has three Base64URL-encoded parts separated by dots: header, payload and signature. This decoder reveals the header and payload claims (such as iss, sub, exp) so you can debug authentication issues quickly.
Frequently asked questions
Does this verify the signature?
No. This tool only decodes the Base64URL header and payload so you can read the claims. It does not validate the signature.
Is it safe to paste a token here?
Decoding happens entirely in your browser. Still, never paste production tokens or tokens you do not own into any online tool.
