The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.
An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones.

QEMU uses the .img file extension for raw images of hard drive disks, calling the format simply "raw".
