How to Export Your Chrome Bookmarks (and What the File Contains)

Chrome syncs your bookmarks, which people reasonably take to mean they are backed up. Sync is not backup: it is replication. Delete a folder on one machine and the deletion is faithfully copied everywhere else within seconds.

An export is the thing that actually protects you, and it takes well under a minute.

Exporting

• Open the Bookmark Manager — Ctrl+Shift+O, or Cmd+Option+B on a Mac.
• Click the three-dot menu at the top right of the manager, not the one in the browser toolbar.
• Choose Export bookmarks.
• Save the HTML file somewhere that is itself backed up.

The same menu has Import bookmarks, which reads the identical format. Every major browser imports and exports it, which is the one genuinely good thing about this ageing file format.

What is in the file

Open it in a text editor and you will find a nested list of links. Each entry carries the title, the URL, the folder it lived in, and an ADD_DATE timestamp in Unix seconds. Some entries carry a base64 favicon.

That is the whole of it. Which means it is worth being clear about what is not in there:

• No page content. Not a word of the articles. The file is addresses, and an address to a deleted page is a dead entry in a backup.
• No notes. Chrome has nowhere to put why you saved something, so there is nothing to export.
• No tags. Folders only, and a bookmark lives in exactly one.
• No record of what still works. Dead links export exactly like live ones.

What the export is good for

Three things, honestly:

• Moving browsers. It is the universal format, and this is the job it does well.
• A point-in-time snapshot. Protection against your own mistakes and against sync faithfully propagating them.
• Auditing. The export is the input a bookmark checker reads to tell you which links have died.

What it is not good for is the thing people most want: having the content later. A bookmark backup is a backup of pointers, and it ages at exactly the rate the web does.

If you want the content, not the address

For links you genuinely intend to return to, the export is the wrong tool and no amount of backing it up changes that. What survives is a copy of the page, taken while it was still there.

That is the gap SocialClipper fills for social posts in particular — it saves the text, the images and the video rather than the URL, so a deleted post is still readable.
