I would like to upload all the books I have stored in my calibre library to kindle's cloud so that I can synchronize my reading (whispersync "sync to last page read" function) across my android and kindle voyage. Is this possible?
I have seen the email to kindle function but have read that this can cost money and am unsure if I will have to do each book individually. I live in Australia and am confident with calibre use. None of my books have DRM.
This link provided by Woeitg: http://the-digital-reader.com/2015/02/07/upload-ebooks-documents-kindle-account/ Cleared up my confusion about emailing to kindle costing money. It seems this only applies only to kindle devices using 3G. appending the '.free' to the email ensures only wifi is used and no charges are applied.
