Questions
Is it safe to paste a real token?
It never leaves your browser. Still, treat tokens like passwords and avoid sharing live ones.
Does it verify the signature?
No. Checking a signature needs the secret or public key, which only the issuing server should have.
Is my data private?
Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.
Is it free?
Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
