Window Zoom is a free Chrome extension developed by ilgit.yildirim. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This extension allows users to easily zoom all the tabs in a specific browser window simultaneously.

The main purpose of Window Zoom is to provide a convenient solution for users who work with multiple screens that have different resolutions. The extension eliminates the need for fractional settings, which can often consume more GPU resources and cause issues on certain operating systems, especially Linux.

With Window Zoom, users can simply set a zoom level for a specific window, and all the tabs within that window will be zoomed accordingly. This eliminates the hassle of adjusting the zoom level tab by tab, saving valuable time and effort.

It's worth noting that if a tab is moved from a zoomed window to another window, it will automatically reset itself back to the default 100% zoom. On the other hand, if a tab is added from a non-zoomed window to a zoomed window, it will be zoomed automatically.

Window Zoom does not apply the zoom settings per-origin, meaning that if you visit the same site on another window, it will have the default zoom settings (usually 100% with no zoom).

Overall, Window Zoom is a useful Chrome extension for users who frequently work with multiple screens and want to easily manage the zoom levels of their browser windows and tabs.
