FAQ

Frequently Asked Questions

Does decoding a JWT verify it?

No. Decoding only reads the token content. Signature verification is a separate step.

Can anyone read a JWT payload?

Yes, if they have the token. Do not put secrets in the payload.

What does exp mean in JWT?

The exp claim usually stores the token expiry time as a Unix timestamp.

Is JWT Decoder free to use?

Yes. JWT Decoder is free to use on ToolsLuv for quick developer checks, formatting and copy-ready output without creating an account.

Does JWT Decoder upload my snippet?

JWT Decoder is designed as a browser-first utility for everyday snippets. Still, do not paste passwords, private tokens or sensitive customer data into any online tool.

Is this tool private?

Yes. The work runs in your browser, so your input is not uploaded to a server by ToolsLuv.
