Why convert to EPUB?

While PDFs are great for preserving exact layouts and graphics, they don't adapt well to small screens. EPUB files are "reflowable", meaning the text automatically adjusts to fit your screen size, allowing you to change fonts, text size, and margins on your eReader or mobile device for a much more comfortable reading experience.
