How to Duplicate a Chrome Window (With All Its Tabs)

You want a second window with the exact same tabs open — same pages, same order, original window left exactly as it is — maybe to compare two states of a project, hand one off, or just keep a backup layout before you start closing things. Chrome doesn't have a "Duplicate window" button anywhere in its menus. The workaround takes a few extra clicks, but it's reliable.

Why there's no native "Duplicate window" command

Chrome can duplicate one tab at a time — right-click it, choose Duplicate, and a copy opens next to it. That single-tab building block is as far as the built-in feature goes; there's no version of it scoped to "every tab in this window." See How to Duplicate a Tab in Chrome for the mechanics of that single-tab action, including what does and doesn't carry over to the copy.

The actual workaround: duplicate each tab, then move the copies

1. Duplicate every tab in the window. Right-click each tab and choose Duplicate. Chrome adds a copy directly next to the original, so the window now has two of everything, interleaved.
2. Select just the duplicates. Hold Ctrl (Cmd on Mac) and click each duplicate tab to add it to a selection, without touching the originals. See How to Select Multiple Tabs in Chrome at Once if you haven't used multi-select before.
3. Move the selection to a new window. Right-click any one of the selected duplicates and choose Move tabs to a new window. Every selected tab relocates together, in the order you selected them, into a brand-new window.

The original window is untouched throughout — duplicating and moving only ever act on the copies you created in step 1.

What doesn't carry over to the new window

• Tab groups. A duplicated tab is a plain tab, even if the original sat inside a colored, named group. The new window's tabs land ungrouped; you'd have to re-create any groups by hand.
• Pinned state. Duplicating a pinned tab does not pin the copy. If pin order matters in the new window, you'll need to re-pin the relevant tabs there.
• Live page state. Same as any duplicate — scroll position and unsaved form input reset, since Chrome loads a fresh copy of the URL rather than cloning the tab's live DOM. Login sessions do carry over, though, since duplicates share the same profile's cookies as the originals.

When this isn't actually what you need

If the goal was really "I want to come back to this exact set of tabs later," duplicating a window is solving the wrong problem — it doubles your open-tab count for something that doesn't need to stay open at all.

Amazing Tabs saves a whole window's tabs as a named collection you can reopen anytime, without ever having a second copy cluttering your tab strip in the meantime:

• Save every tab in a window with one click, then close the window with nothing lost.
• Search it back instantly with ⌘K / Ctrl+K whenever you need that set of tabs again.
• Free for up to 100 saved links, with optional cross-device sync on paid plans.

Quick recap

• Chrome has no native "Duplicate window" command — only single-tab duplication.
• The workaround: right-click-Duplicate every tab, Ctrl-click to select the copies, then "Move tabs to a new window" to consolidate them.
• The original window is never touched by this process.
• Tab groups and pinned state don't carry over to the duplicated tabs — only the page itself does.
• Login sessions do carry over, since duplicates share the same Chrome profile as the originals.
