Frequently asked questions
Is JWT Expiry Checker free to use?
Yes. JWT Expiry Checker is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does JWT Expiry Checker upload your file to a server?
No. JWT Expiry Checker processes your file inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a limit on how much input I can use?
JWT Expiry Checker handles inputs into the megabytes without trouble; the only real limit is how much your browser tab can hold in memory.
Do I need to install anything to use JWT Expiry Checker?
No installation is needed. JWT Expiry Checker runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use JWT Expiry Checker on a phone or tablet?
Yes. The JWT Expiry Checker interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. JWT Expiry Checker keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
