This runs in the Acrobat app - there is no separate API for this task.
The 'Changes Allowed' options let you control what users can do to your PDF. For example, you can stop them from adding or deleting pages, filling out forms, or taking out parts of the document. This is important for keeping your document's content safe and unchanged. If you choose 'None', no changes can be made without the owner password. This helps protect the document's integrity.
Yes, restricting editing does not automatically stop copying. The 'Restrict printing, editing, copying' feature has separate options. You need to make sure you also set the copying restriction to 'None' if you want to prevent text from being copied. Always check all the settings to fully protect your document.
An owner password is like a master key. It lets you, the owner, change or remove the restrictions you put on the PDF later. Without it, even you cannot change the settings once they are applied. This ensures that only authorized people can modify the document's security, keeping your content safe.
No, you cannot remove PDF protection if you have forgotten the owner password. The owner password is required to change or remove any restrictions. This is a security measure to protect the document's content. Always keep your owner password in a safe place, as there is no built-in way to recover it if lost.
