A TIFF file, which stands for Tag Image File Format is a type of computer file that's really good at storing high-quality pictures and images. It's like a digital photo album for your computer. What makes TIFF special is that it keeps all the details and colours in a picture exactly as they are, so it's excellent for things like professional photography, artwork, and documents where you want the best image quality. It's like having a photo that doesn't lose any quality when you save it on your computer, making it great for important and detailed pictures.

TIFF files:
