Back up favorites | Microsoft Edge
In Microsoft Edge, website bookmarks are favorites. If you sign in to the browser with a Microsoft account, you can turn on syncing and automatically save your favorites to the cloud. If you don’t want to sign in to the browser or would rather have a local copy, you can back up your Edge favorites to your local hard drive, USB drive, SD card, or anywhere else you like.
Here's how to back up Microsoft Edge favorites:
