Adding Content Files ← Knowledge Base What file types are accepted by NetGalley? How do I upload content files? What reading devices does NetGalley support? Can I add a content file directly into NetGalley? Can I add content files before the title records are created? How can I tell if my pdf/epub has imported? Can I replace content files? I got an error message that my file isn't ready, or there may be a problem. What happened? Can I add an illustrated or image-heavy title to NetGalley?
