A RAW file contains unprocessed image data captured by the digital camera. JPEG files photos and compresses them to be smaller. The bigger file is the RAW because it doesn’t compress the images and are used to take huge photos. You can turn RAW images into JPEG images by using Adobe Lightroom to edit and export them into a JPEG file. If I was shooting an important event, I would use JPEG because it takes up less storage and can be downloaded faster than RAW images.
