JWT Expiry Checker
- Browser-based
- No signup
Browser-based
Paste a JWT token to see expiration time, time remaining, and active or expired status without sending data to a server.
How to use this tool
Paste your JWT token and review the expiry status, expiration timestamp, and time remaining.
Worked example
Example: a token with exp in the past shows Expired with the exact local date and time it lapsed.
How it works
Paste a JWT (optionally with a Bearer prefix) to focus on its expiry claim. The tool decodes the token, shows whether it is expired, how long until expiry, and the expiration time in your local timezone. Signatures are not verified.
Limitations
Decoding does not verify signatures. Never paste production secrets into shared or untrusted tools.
Privacy and file handling
