No. The magic of eReader devices is that users can customize their reading experience by changing fonts and font size (and sometimes line-spacing, margins, and justification). In other words, text "flows" -- it no longer lives in a fixed position on a printed page. Instead, text flows in sequence according to the user's preferences and what kind of device they own.
Because of this, we want to convert your eBook so that it looks good on ALL devices - from an iPhone to an iPad to a Sony Reader - and also so that it looks good in color (iPad, Nook Color) and black and white e-ink (Kindle).
If you supply a file for a conversion, the following elements will be changed to plain text: drop-caps, tables, multiple columns, call-outs, word art. All images with wrapped text will be changed to in-line images with text above and below. All footnotes will be changed to endnotes.
If you really want it to look like a PDF, you will need a Fixed Layout eBook. https://www.bookbaby.com/fixed-layout-ebooks/
