Share your PDFs and images using Preview on Mac
You can share a copy of a PDF or an image via email, Messages, and Notes. You can also share with other people who are using AirDrop.
Go to the Preview app on your Mac.
Open the PDF or image you want to share.
Choose File > Share (or click in the toolbar), then choose how you want to share your PDF or image.
If AirDrop isn’t listed, your computer doesn’t support it.
Note: If you opened an item stored on iCloud Drive, choose Share File from the pop-up menu to share the item with other iCloud users. See Use iCloud to share and collaborate on files and folders.
