1: Sync 1a: Plug in device via USB, right click, send to device 1b: with your android/ios device connect wirelessly with the calibre companion app, right click, send to device Tips: calibre companion avoid the need to fiddle with a usb cord and worry about your device properly talk to your computer something that is harder than it ought to be with phones/tablets ondevice:false shows you all the books in your library that aren't on the connected device and can be combined with any other query eg tags:scifi and ondevice:false. If its harder than this you may be selected a device that was not only proprietary and shitty but also uncommon so that calibre don't know how to work around its shittiness. 2: right click book book convert individually/bulk convert Tips: If you want to know what things are not in your preferred format say you want epub and not mobi you can search for formats:mobi and not formats:epub. This makes it easy to ensure everything is in a format that for instance works well with your device. Don't expect conversions to and from PDF to work well. If might turn out readable but it wont be optimal. It works MUCH better converting between more standardized ebook formats. 3. You CAN configure calibre to strip DRM on import automatically but this is inherently going to be a continuing struggle because its an arms race. Consider just not buying books that are protected by DRM. You can virtually always get a book without DRM, get a pirated version that doesn't by its nature have DRM, or a physical book. Hell if you like buy a physical book and donate it and enjoy your pirated book without guilt. If you find the interface confusing in the settings you can literally customize - the items that show up in the toolbar - the items that show up in the toolbar when a device is connected - the context menu that pops up when you click a book in each type of view if need be You can further customize short cuts including single key shortcuts If you do 3 things you can have 3 buttons in the toolbar or if you please 3 single character shortcuts. Want e to edit the books info and s to send it to your connected device then configure it so.
