4K-AutoZoom is a practical Chrome extension designed to enhance the browsing experience for users with 4K screens. It automatically adjusts the zoom level of a tab based on the window's size, setting it to 200% when maximized and reverting to 100% for FHD windows or smaller. This feature is particularly useful for those who frequently work with multiple FHD windows on a 4K display, allowing for better visibility of content without manual adjustments.

In addition to its automatic zoom capabilities, the extension also includes a convenient keyboard shortcut (CTRL + UP) that allows users to toggle between 150% and 100% zoom levels. This functionality is aimed at providing a more customizable viewing experience, catering specifically to the needs of users who require detailed views of their work. Overall, 4K-AutoZoom offers a simple yet effective solution for optimizing window management on high-resolution screens.
