Frequently Asked Questions

Why does my PDF application keep forgetting my saved signature?

This is typically caused by a synchronization glitch between the desktop application and cloud services, or by using an outdated version of the software that contains unresolved authentication bugs.

Can I use the Fill & Sign feature offline?

Yes. Once your signatures are locally saved and your account is fully authenticated, you can use basic signing features offline. However, syncing new signatures across devices requires an active internet connection.

How do I recover lost signatures in my PDF tool?

If your signatures disappear, first ensure you are signed in with the correct account ID. Signing out and signing back in, or updating the software, usually forces the app to pull your saved signatures from the cloud.
