Frequently Asked Questions

Is my code sent to a server?

No. All tools on this site run in your browser.

Do I need an account?

No. There is no signup and no watermark.

Does the JWT decoder verify signatures?

No, and it says so on the tool page. Decoding is not verification.

Why is MD5 not offered?

MD5 is not available in the Web Crypto API, so this site does not fake it. SHA-256 is the recommended alternative here.
