Since PDF is an ideal format to save or attach via email, it’s important to use a good tool that lets you easily split PDFs into multiple files online to get pages with useful information.

Breaking a large PDF into separate files allows you to keep a PDF's sensitive information away from those who don't need to see it, while still providing them with the non-sensitive info.

To split a PDF into multiple files in one step, use the Split Document command from the "Tools" menu's "Pages" submenu. You can apply this procedure to open or closed files.
