About this tool
Create JWT tokens from JSON payloads in seconds. Choose HS256 for signed tokens or none for unsigned debug scenarios, then copy the generated token for API testing. This tool pairs naturally with JWT decoder workflows and helps speed up auth debugging in staging environments.
Frequently Asked Questions
Which algorithms are supported?
This version supports HS256 and none, which cover most local debugging and test integration scenarios.
Do you store my JWT secret?
No. Secrets and payloads are processed client-side and are never sent to a backend service.
Can I use generated tokens in production?
Use caution. This tool is primarily for development and testing; production signing should run in secure backend infrastructure.
