How to move Arc bookmarks and spaces to Chrome

Updated 18 October 2026

Arc has no export button, and Chrome’s import window doesn’t list Arc. Your spaces, pinned tabs and folders live in one file, StorableSidebar.json, and our free Arc bookmarks exporter turns it into a normal bookmarks file that Chrome imports, with one folder per space.

Why there’s no direct route

Chrome’s Import bookmarks and settings window reads Firefox, Safari on a Mac, Internet Explorer on Windows and bookmarks HTML files. Arc isn’t on that list, and Arc only imports from other browsers. Many people are moving now that Arc only gets maintenance: The Browser Company said in May 2025 that it had stopped building new Arc features while it works on Dia, and keeps Arc going with Chromium upgrades and security fixes. In October 2026 arc.net says Arc receives Chromium updates only.

Step 1: copy Arc’s sidebar file

Copy it to your desktop and work with the copy. Arc can stay open while you do this.

Step 2: turn it into a bookmarks file

1. Open the Arc bookmarks exporter and drop the copy onto it. The page reads the file in your browser and uploads nothing.
2. Check the preview. Each space is a folder, pinned tabs and folders keep their nesting and order, and tabs that were open below the divider sit in an Unpinned tabs subfolder inside their space.
3. Download the bookmarks file (.html).

Step 3: import it into Chrome

1. Open chrome://bookmarks (Cmd+Option+B on a Mac, Ctrl+Shift+O on Windows).
2. Click the three-dot menu at the top right, choose Import bookmarks and pick the file.
3. Look at the end of the bookmarks bar for a folder named Imported with your spaces inside, one folder each. On a fresh Chrome with an empty bar, the space folders land on the bar itself.

Don’t need the open tabs you had in Arc? Delete the Unpinned tabs folders and keep the rest.

What doesn’t come across

• The Favorites row of icons at the very top of Arc’s sidebar is stored differently and may be missing. Add those few sites by hand.
• Notes, Easels, Boosts and Little Arc windows aren’t bookmarks, so they stay in Arc.
• History and saved passwords aren’t in the sidebar file, and Chrome has no Arc importer to fetch them.

Getting spaces back in Chrome

Chrome has no sidebar spaces. Its nearest built-in tools are profiles, which keep everything separate, logins included, and saved tab groups. If what you liked was a home for each area of your life, our extension Stackboard can rebuild that on the new tab page. Download the Stackboard backup (.json) from the same exporter, then in Stackboard open Settings > Backup > Import JSON. Each Arc space becomes a Stackboard space, its folders become stacks, and everything is saved as ordinary Chrome bookmarks that sync with your Google Account. Your open tabs stay in Chrome’s normal tab strip; Arc spaces in Chrome covers what this replaces and what it doesn’t.
