Which still image file type is typically larger in file size due to its high quality?

The choice of .tiff as the still image file type that is typically larger in file size due to its high quality is accurate because TIFF (Tagged Image File Format) is designed specifically for high-quality images and is often used in professional settings where image fidelity is paramount, such as in photography and publishing. This file format supports lossless compression, meaning it retains all the original image data, which results in larger file sizes compared to formats that use lossy compression, such as JPEG.

Additionally, TIFF files can store extra information about the image such as layers and color profiles, further contributing to the increased file size. This makes .tiff ideal for editing and printing, where image quality cannot be compromised. Other formats like JPEG and GIF use compression techniques that reduce file size at the expense of image quality, while PNG files, while lossless, still generally do not reach the larger sizes seen with TIFFs, particularly when dealing with complex images.
