Many iPhone users are looking for aae to jpg conversion, because they are attempting to somehow recover photos (.jpg files) from .aae metadata files, something that is actually not possible. This is due the fact that .aae file does not contain the picture itself, so there is nothing to recover. Each .aae file is generated for a specific .jpg file and contains changes made to the photo using the Apple Photos app. You have to look for the actual JPEG files, if you do not have them, or have their backup, then it is not possible to recover jpg pictures from aae files.
