FAQ
Does this verify the JWT signature?
No. This tool focuses on decoding the payload and checking the exp claim, not cryptographic verification.
Is the token uploaded anywhere?
No. Decoding happens in the browser so the workflow stays lightweight and local.
How it works
Paste a JWT to inspect its payload, expiration time, and remaining lifetime without sending the token anywhere. The result is produced immediately so you can review it before copying or using it elsewhere.
Privacy
The tool is designed to process ordinary input in your browser. Avoid pasting passwords, private keys, access tokens, personal records, or other sensitive production data into any online utility.
Limitations
This utility handles the focused workflow described on this page. Check the result before production use, especially when an input depends on a vendor-specific format, security rule, or external standard.
