How do you change a photo from JPEG to RAW?
It is not possible to convert a JPEG file into a RAW format file. This is because a RAW file is a lossless recording of all the data received by the camera from the sensor and a JPEG file is a lossey compressed file containing only a fraction of this information. For this reason, the JPEG file would not contain enough data in order to recreate the amount required to generate a RAW file. RAW files can only be created directly by a camera as the image is recorded.
