If you imported browser data into Safari on your Mac and now see repeated bookmarks, compare the imported links with your existing ones, then delete only the extras in Safari’s bookmark controls. Safari can import bookmarks more than once, but Apple’s documented controls do not include an automatic duplicate finder or one-click deduplication command.

Check where the duplicates came from

Safari can import bookmarks directly from Chrome or Firefox, and it can import bookmark files exported from several browsers. Apple says imported bookmarks appear after existing bookmarks; manual imports are available even if you have imported before. That makes a second import a likely cause when the same sites appear in the library twice. Import bookmarks and history directly from another browser in Safari on Mac

Before deleting, open Safari and choose Bookmarks > Edit Bookmarks, or open the sidebar and select Bookmarks. Expand folders and look through the area where the imported items were added. If you are unsure which copy is new, compare its folder location and address with the imported source. Keep the copy in the folder you actually use, especially if folders represent different purposes.

Identify true duplicates before deleting

Two bookmarks are duplicates when they lead to the same destination and you do not need both copies in separate folders. Matching names alone are not enough: a site can have several useful pages with similar titles. Conversely, the same page can have a different title or a slightly different address, such as a tracking parameter or a different version of the URL.

Open each candidate and compare its destination. Also consider whether the link includes a path to a specific article or account page; those are different bookmarks even if they share the same site name. Keep a copy if it is the only one in a useful folder, or if its address preserves a page you want. Safari lets you edit a bookmark’s name and website address, move it to another folder, and delete it from the sidebar or the Edit Bookmarks view.

Delete extra bookmarks in Safari

In the Safari sidebar, select Bookmarks. If the sidebar is hidden, use the Sidebar button in the toolbar. Control-click the specific extra bookmark and choose Delete. Repeat for each confirmed duplicate. You can also manage bookmarks by choosing Bookmarks > Edit Bookmarks; use that view to inspect the folder structure and remove selected extras. Apple documents deletion of an individual bookmark or a folder, so take care not to delete a folder that contains unique links. Delete a bookmark in Safari on Mac

If the imported duplicates are grouped in their own folder and every item there is an unwanted repeat, verify the contents first, then delete that folder. If only some items repeat, delete those bookmarks individually and retain the rest. Safari’s folder and sorting controls can help you review the library, but sorting by name is an aid for inspection, not proof that links are duplicates.

If you imported into Chrome instead

In Chrome on Mac, open More > Bookmarks and lists > Bookmark Manager. Review the imported folder alongside the existing folders, then use the menu for an individual bookmark and choose Delete for the confirmed extra. Google warns that deleted Chrome bookmarks cannot be recovered, so double-check the link and folder before removing it. Chrome’s documented manager supports editing, deleting and sorting bookmarks; its guidance does not describe an automatic duplicate-removal feature. Create, find and edit bookmarks in Chrome

Prevent another duplicate import

Do not repeat the import merely to add a few missing bookmarks: Safari’s manual import can be run again, and it does not promise to merge duplicates. Add missing links individually, or review an export before importing it again. If you use an exported data file, remove it after importing if it may contain sensitive browser data; Apple notes that imported and exported files may include unencrypted information.

After cleanup, revisit the folders you changed and open a few retained links to confirm the right destinations remain. For future imports, import once, check where the bookmarks landed, and compare against your existing collection before deciding what to keep.
