Image files can be of different formats. Some of the popular ones include BMP (8-bit, 24-bit, 32-bit), PNG, JPG (JPEG), GIF, PPM, PNM, and TIFF. We do not need to be worried about the specific format of an image file (and how the metadata is stored) to extract data from it. Python image processing libraries will read the image and extract the data, along with some other useful information for us (for example, image size, type/mode, and data type).
