Merge several bookmark files into one

Updated 18 October 2026

Got bookmarks spread over a laptop, a work computer and an old browser? Drop all the exports here. Folders with the same name merge into one, duplicates go, and you import a single file.

Good to know

Folder names match regardless of case, so “Work” and “work” merge. Firefox’s “Bookmarks Toolbar” and Chrome’s “Bookmarks bar” have different names, so they stay apart unless you rename one in its file first.
The first file you add wins when two links are duplicates, so add your main browser’s export first.
It reads HTML exports from any browser plus Chrome’s Bookmarks file, Firefox JSON backups and Stackboard backups, in any mix.

Export your bookmarks from Chrome first

Open chrome://bookmarks (Ctrl+Shift+O, or Cmd+Option+B on a Mac).
Click the three-dot menu at the top right and choose Export bookmarks.
Save the .html file, then drop it into the box above.

Edge, Firefox, Safari, Brave, Opera and Vivaldi export the same kind of file. The full walkthrough, with backups, is in how to export Chrome bookmarks; for the others see Edge, Firefox, Safari, Brave and Opera.

Import the file into Chrome

Open chrome://bookmarks (or press Ctrl+Shift+O, Cmd+Option+B on a Mac).
Click the three-dot menu at the top right of the Bookmark Manager and choose Import bookmarks.
Pick the .html file you downloaded. Chrome adds everything in a new folder, usually called Imported at the end of your bookmarks bar (look under Other bookmarks if it isn’t there), and your existing bookmarks stay as they are.

Edge, Brave, Firefox and Safari read the same file. Step-by-step versions: Chrome, Edge, Brave, Firefox and Safari.

Questions

How do I combine bookmarks from two computers?

Export the bookmarks on each computer, bring both files to one machine, merge them here and import the merged file. If both computers use Chrome with sync, they already share bookmarks once you sign in to the same account.

Will it merge Chrome and Firefox bookmarks?

Yes. Both export the same HTML format. Rename Firefox’s top folders in the file if you want them to merge with Chrome’s.

Is my file uploaded anywhere?

No. The page reads the file with your browser’s own file reader and builds the new file on your computer. You can load the page, turn off Wi-Fi and it still works.

Your bookmarks, on every new tab

Stackboard is a free Chrome extension that lays out your bookmarks as a board on the new tab page. It stores everything as ordinary Chrome bookmarks, with no account.
