## FAQ

### Can this recover a forgotten password?

No. You need the password that opens the PDF.

### Is my password uploaded?

No. It is used only in this browser tab while creating the unlocked copy.

### Why does an unlocked PDF still have restrictions in some readers?

Some readers cache file state or enforce signature policies. Save the exported file under a new name and reopen it.
