about this task

Open your PDF in Acrobat.
Go to the security settings for restricting printing, editing, and copying.
Under 'Printing Allowed', select 'None'. This will prevent anyone from printing your document.

When you restrict a PDF, 'Changes Allowed' lets you choose what types of edits people can make. This includes actions like inserting new pages, deleting existing pages, rotating pages, filling out forms, or taking out parts of the document. Setting this helps protect your content from unwanted changes.

The 'Restrict printing, editing, copying' feature controls various actions. While the facts focus on printing and editing, copying text is often linked to editing permissions. If you set 'Changes Allowed' to 'None', it typically includes preventing copying as well. Always test your settings to ensure the desired level of protection, as some viewers might behave differently.

An owner password is like a master key for your PDF's security settings. It is needed to change any restrictions you put in place, such as printing or editing limits. This ensures that once you lock down a document, only you or someone with the password can unlock or alter those specific security rules, keeping your content safe.
