The feature in macOS that allows you to preview and edit files without opening them is Quick Look. This convenient functionality gives users the ability to quickly view the contents of files—such as images, documents, and videos—by simply selecting the file and pressing the space bar. Quick Look provides a fast and efficient way to check the contents of a file without the need to open it in the corresponding application.

Quick Look also supports basic editing features, such as marking up PDFs or images, allowing users to make quick adjustments directly from the preview interface. This enhances productivity as it saves time by reducing the number of applications that need to be opened for simple tasks.

The other options, while relevant in their own contexts, do not serve the same purpose: Preview is primarily for viewing files and images, QuickTime is mainly a media player for viewing and editing video files, and Core Image is a framework used for processing images, not a feature designed for quick file previewing.
