Questions

Does this verify the signature?

No. It only decodes the token. Anyone can read a JWT’s contents — signature verification needs the secret or public key and should happen on your server.

Is it safe to paste a real token?

The token is decoded locally and never sent anywhere. Still, treat live tokens like passwords.
