When you upload a PDF, we do not do any processing on it.  We simply sell your PDF.

The same is true with EPUB uploads via our "Upload" writing mode. Our Upload workflow is exactly that: you make the book, we sell it.
​
When you use our book generation workflow, then we output an ebook in PDF and EPUB (and HTML for reading online), like the many you see in our store here:

​
If you want a representative example of what one of these books looks like, you can download R Programming for Data Science for free from
​https://leanpub.com/rprogramming

(You can also buy it for money, of course -- it's a great book!)
