Does Apple convert HEIC images to JPEG automatically when uploading

Hello, I'm web developer and I'm trying to place uploaded images on a map with the EXIF data (GPS coordinnates). The problem is that on iPhone, HEIC/HEIF images are directly converted to JPEG on upload and EXIF metadata are not retrieved. There is a workaround to this ? Thanks in advance.
