Any JPEG file’s size is the primary distinction between it and a RAW file. RAW picture file formats are much larger than JPEG (and other) image file formats. This is due to the fact that they are entirely uncompressed and contain all the original image data that was recorded by the sensors in your digital camera.
RAW versus JPEG, which file size is larger? Between two and six times as big as a JPEG file is a RAW file. RAW files are larger because they have a lot more image data in them. All of the information is essentially condensed into a JPEG image, which has a smaller file size and is simpler to transfer.
