Adobe recently released Lightroom Downloader, a Windows 10 & macOS v10.13 application that allows you to download all synced Lightroom photos to a folder on your hard drive.
Notes (from Adobe):
- The app downloads all your Lightroom photos and videos from the cloud as original files and writes them into a date-based folder hierarchy at the hard-drive location that you specify.
- The edits made to the raw images are written into the XMP sidecar files that accompany the downloaded raw files.
- For the photos originally uploaded from the Lightroom Classic CC desktop app that only have a Smart Preview synced to the cloud, the app downloads DNG Smart Previews only for such photos.
