Exporter for Aperture is a great way to back up your Aperture Libraries in a format that is not reliant on the future use of Aperture. Exporting will always generate files for your originals without adjustments. Versions with Aperture adjustments baked-in can be generated optionally.

Migration:

• Exporter for Aperture was designed specifically for Aperture users who have decided to move to Lightroom. With only a few options and a click of a button, Exporter for Aperture re-generates your Aperture Library as a set of folders and subfolders containing your images.
  Moving to a photo management tool other than Adobe’s Lighroom? Don’t worry, we probably have you covered too.

Features:

• Export your Aperture library to a set of folders
• Retain meticulously crafted project hierarchies.
• Keep all your metadata including ratings and comments.
• Convert identified Aperture Faces to keywords.
• Original/Master images saved with XMP sidecar files for ultimate compatibility.
• Aperture adjusted images saved as TIFF or JPEG depending on image rating. Adjustments are baked-in the image.
• Exports images contained in your albums and smart albums.
• Converts Aperture flags and color labels to keywords.
• Your Aperture libraries are unaltered and unaffected.
