FAQ
FAQ
Does the JWT decoder verify signatures?
No. It decodes JWT header and payload content only. It does not verify whether a token is trusted.
Are these tools meant for production secrets?
Avoid pasting secrets into any web tool. These utilities run locally, but sensitive secrets should still be handled carefully.

Can non-developers use some of these tools too?
Yes. Product managers, QA and technical writers often use developer utilities for inspecting payloads, formatting snippets and checking encoded values.
