To convert a JPG file to a RAW file, you will need to use specialized software or tools designed for this purpose.

Keep in mind that the conversion may result in some loss of image quality, as RAW files contain more data and information than JPG files.
.jpg is a picture format.
you should use software coverter jpg to pdf, you can search with keyword jpg to pdf on google
To open a jpeg (.jpg) file on a Mac the user is required to double click on the file's icon.

Most common graphic file extensions are: .jpg .jpeg .png .gif (for animated images)
