Is there any risk associated with converting a book from say epub -> AZW3, or AZW3 -> EPUB?
And specifically in the case of epubs, are there formats which are closer in file structure, therefore safer or 'better' to convert to?
Context: I'm a calibre-web user and I am finding that the 'send to ereader' button does not appear for some of my epubs until I convert them from epub to another format and then back to epub.
