Frequently Asked Questions

Are these dev tools free?▼

Yes. All dev tools are completely free. No signup, no account.

Is my data sent to a server?▼

No. Base64 encoding, URL encoding, JWT decoding, hash generation, and regex testing all happen in your browser. Your tokens and secrets stay on your device.

Can I decode JWTs safely?▼

Yes. JWT decoding happens entirely in your browser. The token never leaves your device. Only the header and payload are decoded — signatures are not verified server-side.
