To change the order of PDF pages in Preview on macOS, you'll use the thumbnail or contact sheet view and drag the pages to their desired positions. Here's how:
Steps to Reorder PDF Pages in Preview
-
Open the PDF: Open the PDF document you want to modify in the Preview application.
-
Choose the View: Select either Thumbnails or Contact Sheet view:
- Go to View in the menu bar.
- Choose either Thumbnails or Contact Sheet. Both options will display page previews along the side of the window.
-
Drag and Drop Pages: In the sidebar showing the page thumbnails, click and drag the thumbnail of the page you want to move to its new location. A line will appear, indicating where the page will be inserted when you release the mouse button.
-
Release the Mouse Button: Once the page is in the desired position, release the mouse button. The page will now be in its new order within the PDF.
-
Save the PDF: Go to File > Save (or File > Export as PDF...) to save the changes.
Moving Pages Between Different PDFs
You can also move pages from one PDF to another using a similar method:
-
Open Both PDFs: Open both PDF documents in separate Preview windows.
-
Choose the View: In both PDF windows, select either Thumbnails or Contact Sheet view (View > Thumbnails or View > Contact Sheet).
-
Drag and Drop: Click and drag the thumbnail of the page you want to move from one PDF's sidebar to the sidebar of the other PDF.
-
Release the Mouse Button: Release the mouse button when the page is in the desired location in the target PDF.
-
Save the Modified PDFs: Save both the original and the modified PDFs to preserve the changes.
By following these steps, you can easily rearrange and manage PDF pages in Preview.
