Making an EPUB Comfortable to Read as a PDF
An EPUB reflows to fit any screen, while a PDF has fixed pages. Choosing the page size and margins is therefore the main decision, and it should follow where you will read the file.
Matching page size to the device
- A5 with standard margins: close to a paperback, and comfortable on tablets held upright.
- A4 or US Letter: better for printing on ordinary paper or for reading on a laptop. Lines run long, so a wider margin helps readability.
- Compact (4mm) margins: fits more text per page, but is hard to read on paper and leaves no room for binding or hand notes.
If the output looks wrong
Check that the file is DRM-free. A protected book will not convert, as the existing notes on this page explain. Very large books are processed in browser memory, so close other heavy tabs and keep this one open until the download appears. If a book contains a lot of images or unusual styling, review the PDF before you rely on it, because the converter concentrates on text, headings and chapter order.
Next steps
Long books can produce a large PDF. If you plan to share it, use the PDF Compressor. To pull out a single chapter, cut the pages you want with the PDF Splitter. Keep your original EPUB as well; it remains the better format for reading on dedicated e-readers.
