How to Format the PDF Correctly Before You Convert PDF to ePub

The first step to making an ebook is creating a PDF file. Almost any document can be converted to PDF format. Most PDF files are created in a word processor such as Microsoft Word.

The trick to creating a PDF file that converts properly into ePub is to set up the pages in a way that can be read by an e-reader and to use the word processor’s built-in formatting styles. Here are a few tips:

  • Use styles to format headings, indented paragraphs, numbered lists, and bullet lists.
  • Use page breaks when you intentionally want a page to stop at a particular spot (for example, at the end of each chapter).
  • Choose an 8.5” x 11” page size with a portrait orientation and .5-inch margins.
  • Left align or center align the paragraphs.
  • Use a single font for the text. Recommended fonts are Ariel, Times New Roman, and Courier.
  • Use 12 pt font size for body text and 14 pt to 18 pt for headings.
  • Create images in JPEG or PNG format with a maximum size of 600 pixels tall and 550 pixels wide. Images should be in RGB color mode and 72 DPI.
  • Do not wrap text around images. Use inline images where the text is above and below the image.

If you use Microsoft Word, select File > Export to create a PDF file from a Word document.
