4K-AutoZoom is a Chrome extension that automatically adjusts the zoom level of tabs based on their size. When a tab is maximized, it sets the zoom level to 200%, and when resized to a Full HD window or smaller, it adjusts it to 100%. This feature is particularly beneficial for users with 4K screens managing multiple Full HD windows who occasionally need to zoom in for detailed viewing.

The extension aims to enhance user experience by simplifying the zoom adjustment process, catering to those who work with high-resolution screens and multiple windows. With a focus on practicality, 4K-AutoZoom ensures seamless transitions between different tab sizes, providing a hassle-free browsing experience.
