===Editing PDF documents===

Preview can encrypt PDF documents, and restrict their use; for example, it is possible to save an encrypted PDF so that a password is required to copy data from the document, or to print it. However, encrypted PDFs cannot be edited further, so the original author should always keep an unencrypted version. A new "edit button" where the picture can be edited is introduced in Version 7. The "edit button" allows options to insert shapes, lines, do cropping, and among other things.

Some features which are otherwise only available in professional PDF editing software are provided by Preview: It is possible to extract single pages out of multi-page documents (e.g. PDF files), sort pages, and drag & drop single or multiple pages between several opened multi-page documents, or into other applications, such as attaching to an opened email message.
