Microsoft makes it easy to import your favorites from another browser or file into Edge:
Open Microsoft Edge and select Favorites > click the 3 dots > Import Favorites. Or paste this address into the Edge address bar: edge://settings/importData
Under Import from, select the browser from which you want to import your favorites or select Favorites or bookmarks HTML file.
Choose what you want to import from the browser or choose the file you want to import. If importing from Google Chrome also select your profile.
When the import is complete, you'll see a notification. Select Done.
- If you imported from a file, you'll find your imported favorites in a folder on the Favorites bar. The folder may be called Imported.
