Arc Easels and Boosts: what you can save

Neither Easels nor Boosts come over to Dia or any other browser (Arc Help Center).

Easels: save each as a PNG

Open the Easel.
Click the Share icon (bottom-right) > Share Via… and save it as a PNG.

Easels are stored with your Arc account, so they're gone after Dec 22, 2026 (source). A PNG keeps the look, not live links or editable items; copy anything you need to keep editable into a notes app by hand.

Boosts: rebuild them

Boosts can't be exported (source). Open each Boost in Arc now and copy its CSS/JS into a text file. Then recreate them with:

Stylus (CSS userstyles; Chrome, Edge, Brave, Vivaldi, Firefox, Zen).
Stylebot (CSS with a visual editor; Chromium browsers).
Tampermonkey or Violentmonkey for JavaScript Boosts.

Copying Boost code out of Arc's editor works per Boost; there is no bulk export we could confirm (unverified whether any community tool does it).

FAQ

Can I export Arc Boosts?

No. The Arc Help Center says Boosts can't be exported. Copy each Boost's code manually and recreate it with Stylus or a userscript manager.

How do I export Arc Easels?

Open each Easel, then Share > Share Via… to save a PNG. That's the only official option.

Want it done in one sitting?

Everything above is free. If you'd rather follow one checklist with tested scripts (Mac and Windows) and a verification step, the Arc Migration Kit is $12 with a 30-day refund. You don't need it if the free route works for you.
