Frequently asked

Can I pipe the output of JWT Decoder into another tool on this site?
Absolutely. Copy the result, open the next tool, paste. Every tool accepts plain text input, so chaining is straightforward.
Is it safe to use JWT Decoder with private data?
Yes. Because JWT Decoder never transmits your text anywhere, even confidential material stays on your device. Closing the tab wipes it.
Do I need an account to use JWT Decoder?
No account, no email, no login. Just open the tool and use it. There is nothing to register for.
Can I process tab-separated or comma-separated data with JWT Decoder?
Yes. JWT Decoder treats the input as plain text so TSV, CSV and other delimited formats all flow through as-is.
