  • Split Page: The Split Page tool is used to split one page into several parts for better document management.

PDFelement has received both positive reviews and criticism, and almost all of the main criticism mainly comes from its pricing plans.

However, when the free trial has expired, PDFelement only offers premium subscription plans that can be paid per year or half a year instead of monthly plans, which cost more.

How to Edit a PDF on Mac/iPad

Preview offers six editing tools to make fundamental changes to PDF files:

  • Text Selection: By using this tool, you can select and copy the text content of your PDF files, and then paste it into other documents.
  • Selection: This tool is a supplement feature to the text selection tool because it was designed for selecting non-text content, such as images, annotations, etc.
  • Shape: The shape tool is used to insert a shape (box, oval, or line) in PDFs, and the color and thickness of the line can be changed as per your requirements.
  • Add Text: As its name suggests, you can add new text boxes by using this tool.
  • Notes: The tool is used for adding sticky notes to your documents, making it possible to leave your feedback or comments.
