Bookmark migration field guide
Move bookmarks without turning one mess into two.
Pick two browsers. Get the exact export artifact, destination path, and a migration checklist you can finish without importing twice.
Bookmarks and lists → Bookmark Manager → More → Export bookmarks.
Official export instructions ↗Manage bookmarks → Import and Backup → Import Bookmarks from HTML.
Official import instructions ↗Bookmarks HTMLKeep the source export until the destination is verified.
Never run the same import twice just because the imported folder is not where you expected.
Choose the route
Direct import is convenient. HTML is inspectable.
A direct import wizard can move bookmarks plus selected browser data from an installed profile. A bookmark HTML file is the more transparent route: you can keep a copy, inspect it before import, and use it across browser families.
Both browsers are installed on the same computer.
You want the shortest path and are comfortable with the destination browser selecting the source profile.
You are changing devices, want a backup, or need to inspect the library.
It is the shared format across Chrome, Edge, Firefox, and Safari. It moves bookmarks, not a complete browser identity.
Export paths
Create the portable source file.
Chrome
Open Bookmarks and lists → Bookmark Manager. Open the manager’s More menu and choose Export Bookmarks.
Google source ↗Edge
Open Favorites, enter the favorites manager, open More options, then choose Export favorites.
Microsoft source ↗Firefox
Open Bookmarks → Manage bookmarks. Choose Import and Backup → Export Bookmarks to HTML. Do not choose JSON Backup for a cross-browser move.
Mozilla source ↗Safari
Choose File → Export Browsing Data to File. Select Bookmarks only. Safari creates a ZIP containing Bookmarks.html.
The Safari export can include readable password and payment files. Select bookmarks only for this job, and delete any broader archive after the destination import is verified.
Six-step checklist
A migration you can undo.
Progress is saved only in this browser.
Verification
Do not judge the move by the first folder you see.
Destination browsers often place imports in a new location: Chrome can use the bookmark bar or an imported/other-bookmarks folder; Edge documents an imported folder; Firefox adds HTML imports to the Bookmarks Menu. Search for that container before attempting the import again.
- Compare totals. Use the source browser’s visible count or the local analyzer as a baseline.
- Open nested folders. Test one shallow folder and one deeply nested folder.
- Spot-check destinations. Open several important links; the HTML format does not test whether pages are still live.
- Treat dates as optional. The file may include
ADD_DATE, but the destination UI may not expose or preserve it exactly. - Let sync finish. If the destination browser syncs bookmarks, verify a second device before deleting the source copy.
Common problems
Most migration failures are location or duplication problems.
I cannot find the imported bookmarks.
Look for an Imported, Other bookmarks, Bookmarks Menu, or date-stamped imported folder. Turn on the bookmarks bar or sidebar before importing again.
I imported twice and now everything is duplicated.
Keep the source export. If the duplicate set is contained in a single imported folder, remove that folder and import once. If it has mixed into the library, inspect duplicate destination groups before deleting anything.
Firefox gave me a JSON or JSONLZ4 file.
That is a Firefox restore backup. Return to Import and Backup and choose Export Bookmarks to HTML for a cross-browser file.
Safari gave me a ZIP.
That is the current export container. It includes a standard Bookmarks.html entry. Chrome, Edge, and Firefox can import the extracted HTML file; Rewind’s analyzer can read a bookmarks-only Safari ZIP directly.
My reading list, passwords, or history did not move.
Bookmark HTML is intentionally narrow. Those data types use separate transfer paths. In Safari, Reading List entries are represented inside the bookmark export as a special subfolder, but browser handling can differ.

Before importing
Get a clean baseline from the source file.
The local analyzer counts bookmarks, folders, domains, duplicate destinations, tracking variants, and save dates.
