How to export Arc Spaces, bookmarks and passwords before Dec 22
Arc stops working on December 22, 2026. These are the free, official steps. Sources are linked.
Free options first
Before you buy anything: several official and free tools already move Arc data. If one of these fits, use it. Each note says what the tool misses.
- Dia's official Arc importer (free, Mac + Windows). Imports Spaces (as Profiles), Favorites, pinned tabs, folders, bookmarks, history, passwords, cookies and extensions. Misses: folders inside folders become separate flat Tab Groups (Dia doesn't nest them), and Easels and Boosts don't come over. Arc Help Center
- Arc's official Export Data (free, built into Arc). Saves
Arc Data Export.mdwith every Space, pinned tab and folder as links. Misses: it's a list of links, not a bookmarks file, so no browser imports it directly; passwords, history, Easels and Boosts aren't included. Arc Help Center - Helium's Arc sidebar importer (free, added in Helium 0.10.4.1, Mar 2026). Reads Arc's pinned tabs and folders, not just bookmarks. Misses: Helium has no Spaces, so Spaces can't be kept as Spaces. Helium PR #1067
- Free Arc-to-Zen community tools: arc-to-zen-guide, arc-to-zen, arc2zen. Misses: small, unofficial projects. We haven't tested them, so what each one keeps (nested folders, Favorites, Windows support) is unverified. Read the code before you run it, and make a backup first.
- Vivaldi, Brave, Edge and Chrome: no importer brings over Arc Spaces or sidebar folders. Bookmarks, and on some browsers passwords and history, may import, but Spaces and pinned folders have to be rebuilt by hand or from a bookmarks file.
Key dates: Dec 15 is the last day to request a copy of your Arc data. Dec 22 Arc stops working. Whichever route you pick, do it before then.
Moving to Dia? You don't need to export
Dia imports Spaces (as Profiles), Favorites, pinned tabs, folders, bookmarks, history, passwords and extensions straight from Arc. On Mac use Dia > Import from Another Browser… > Arc. On Windows, quit Arc first. Keep Arc installed until the import finishes. (source)
Export Spaces and tabs (any browser)
- Mac: Arc > Settings > Advanced > Export Data. Windows: Ctrl+, then Advanced > Export Spaces and tabs > Export Data.
- Save
Arc Data Export.md. It has one section per Space listing Favorites, pinned tabs, folders and other sidebar tabs as links. - The file is a list of links, not a bookmarks file. To import it as real bookmark folders, convert it (the kit includes a script) or add the links by hand.
Just need one folder? Right-click it and choose Copy All Links. On Mac, hold Option for Copy All Links as Markdown. (source)
Where Arc keeps your sidebar
Arc stores Spaces, pinned tabs and folders in StorableSidebar.json:
- macOS:
~/Library/Application Support/Arc/StorableSidebar.json - Windows:
%LOCALAPPDATA%\Packages\TheBrowserCompany.Arc_<id>\LocalCache\Local\Arc\StorableSidebar.json
Back it up now. Open-source tools such as arc-export turn it into bookmarks HTML.
Easels and Boosts
Easels: open each one, then Share > Share Via… to save a PNG. Boosts can't be exported. (Arc Help Center)
