NetGalley will provide reasonable, straightforward guidelines for file optimization and preparation. We highly recommend that you follow our optimization suggestions and read through the File Troubleshooting section of this Knowledge Base.
FlightDeck is an inexpensive and easy-to-use service, which helps you more quickly prepare files for sale and for upload to NetGalley. It includes a comprehensive report detailing whether your file will be accepted by NetGalley (as well as major retailers) and explaining everything you need to fix.
Please contact email@example.com if you need help with your files, although we highly recommend FlightDeck.
