LinkedIn Message Archiver is a Chrome extension that adds a one-click Archive button directly to each conversation row in the LinkedIn Messaging inbox. Instead of opening every thread, navigating the overflow menu, and clicking Archive manually, you can archive any thread in a single click — right from the inbox list.
LinkedIn’s built-in archive flow requires three steps for every thread: open the conversation, find the More menu, then click Archive. When you have dozens of threads to clean up, this adds up fast. There is no bulk-archive option and no keyboard shortcut.

The content script observes the inbox list for conversation rows and pins a small Archive button to each one. When clicked, the extension opens that conversation, locates LinkedIn’s native overflow menu, and triggers the Archive action programmatically.

Because it drives LinkedIn’s own UI controls, the archive operation is identical to doing it by hand — just faster. The thread disappears from the inbox immediately, exactly as it would with a manual archive.

The extension requests only the permissions it needs: access to linkedin.com pages, plus tabs, scripting, and webNavigation to inject the content script into already-open LinkedIn tabs and respond to client-side navigation. No user data is transmitted to any external server.
