In XML format, AAE files store the edits applied to a picture. When you change an image on an Apple device, the system creates an AAE extension to the original JPEG instead of saving an entirely new image. Since AAE files are exclusive to the latest versions of iOS and macOS, devices running older versions or other operating systems will not be able to run these files. Therefore, if you open these files on those operating systems, no changes will be applied - the edited pictures will remain in their original format. Before transferring your pictures, you must convert the edits stored in AAE files to JPEG files. There are four ways to do this: · Edit your pictures in any app apart from the native Photos app. AAE files are only available in the Photos gallery. Therefore, if you edit a picture through another app, the changes are saved as a new JPEG file rather than an original JPEG with an AAE extension. · Edit your pictures in the Photos app. Then, send them to yourself via email. You will be able to save the images to your devices as renamed JPEG files. Transfer the JPEG files to another device however you wish. · Share edited pictures through a messenger app such as WhatsApp or Telegram and save them as a JPEG file. · Use third-party software. Plenty of apps and websites can help you convert AAE to JPEG – for example, convertimage.net.
