When can I create my ebook from a PDF?
The Free Plan from Write allows you to create your own ebook starting from a .doc document (files generated by Word and Open Office).
With Premium or Unlimited plans, you can create your own ebook by uploading a PDF file within the application; the generated ebook will be in Fixed Layout, so the file will keep the same layout as the original PDF.
PLEASE BE AWARE: you should publish fixed-layout ebooks only in specific cases and for particularly complex layouts: only in those cases you can start from a PDF file. If your book is mostly text, you'll need to start with a .doc file instead of a PDF.
In this article, you'll find more information about the difference between reflowable and fixed-layout ebooks.
