And with iCloud integration, you can access your images from any device connected to your Apple ID.

Another great feature of Preview is that you can easily annotate PDF files with notes, shapes, arrows, and more. You can also add text to your documents or highlight important sections with different colors. This makes it perfect for taking notes during class or work meetings or marking up documents with feedback during group projects.

This makes it easy to create presentations or reports quickly without having to manually arrange each page individually. And if you need even more power you can use Automator actions to automate common tasks like batch resizing or converting files between different formats such as JPGs or PNGs.
