Frequently Asked Questions

            

                                

                    
                    

                        You can set an owner password (restricts printing, copying, and editing) and/or a user password (required to open the file). Both use 256-bit AES encryption.
                    

                

                                

                    
                    

                        Yes. The options panel lets you choose exactly which permissions to restrict — open, print, copy text, and edit independently.
                    

                

                                

                    
                    

                        256-bit AES is the same encryption standard used by banks and governments. It is currently unbreakable by brute force.
                    

                

                                

                    
                    

                        There is no way to recover a forgotten password. Make sure to store it safely. If you locked a PDF you own and lost the password, our Unlock PDF tool may help if you have the original permissions password.
