iCloud: Archive your contacts
To create an archive (copy) of your iCloud contacts, you can use Contacts on your Mac and Microsoft Outlook on your Windows computer. Your computer must have the iCloud Contacts feature set up.
With the iCloud Contacts web app, you can also export all your contacts in a single vCard. For more information, see Export contact information as a vCard.
Use Contacts on your Mac, or Outlook on your Windows computer, to create an archive on your computer.
On a Mac: In Contacts, click All Contacts at the top of the Groups list, select all contacts, then choose File > Export > Export vCard.
Contacts creates one vCard file (.vcf) containing all of the contacts. To export groups together with contacts in a Contacts archive file, choose File > Export > Contacts Archive.
On a Windows computer with Microsoft Outlook 2016 or earlier: For instructions, open Outlook Help and search for “export.”
