View PDFs and images
You can open PDFs and images in Preview, change how documents are shown in the Preview window, and get information about the files.
Open PDFs and images
From the desktop: Double-click a PDF or image file; it opens in Preview by default. You can also select a file or files, then choose File > Open With > Preview.
From within Preview: Choose File > Open, locate and select the file or files you want to open, then click Open.
To open a file you’ve worked on recently, choose File > Open Recent.
From iCloud: Click iCloud Drive in the Finder sidebar, then double-click the PDF to open it. For more information about working with files in iCloud, see Store your desktop and documents in iCloud Drive.
View PDFs or images
When you open a PDF with multiple pages, you can view thumbnails of all the pages in the sidebar.
Show thumbnails: Choose View > Thumbnails or View > Contact Sheet.
Show a document’s table of contents (if it has one): Choose View > Table of Contents.
Close the sidebar: Choose View > Hide Sidebar.
Show pages in a continuous scroll: Choose View > Continuous Scroll.
Show one page at a time: Choose View > Single Page.
Show two pages side by side: Choose View > Two Pages.
Scroll pages: Swipe up or down on the trackpad using two fingers.
Go to a specific page: Click a thumbnail, or choose Go > Go to Page.
Go to the previous or next page: Click the Previous button or the Next button in the Preview toolbar. (If you don’t see the buttons, choose View > Customize Toolbar, then add them.) If your Mac has a Force Touch trackpad, you can accelerate through the previous or next pages by pressing and holding the button, then adding pressure; the more firmly you press, the faster you move through the pages.
Change how thumbnails are shown
If a window sidebar contains multiple PDFs, you may have trouble finding a particular document. You can collapse a PDF’s page thumbnails so you see only the PDF’s filename.
View thumbnails: Choose View > Thumbnails or View > Contact Sheet.
Sort thumbnails: Control-click a thumbnail, then choose an item from the Sort By submenu in the shortcut menu.
The thumbnails are sorted by file. You can’t sort PDF page thumbnails within a PDF.
Change the size of the thumbnails: Choose View > Thumbnails, then drag the sidebar’s separator to the left or right to change the width of the sidebar.
Collapse or expand PDF thumbnails: Click the arrow next to the PDF’s filename in the sidebar.
