Like the argument of “digital books vs. real books,” the comparison between PDF and ePub, the two most important digital formats, has never stopped.

This article is going to differentiate ePub and PDF and help you better use and read the two formats.

What Does PDF Stand for?

The full computer term of PDF is Portable Document Format. Adobe developed it in the 1990s to show various contents, including texts, images, graphics, and interactive content, in a fixed format.

As it can show the same form in whatever device with software handling PDFs, many sectors (business, medicine, government and education) choose to present information in PDF, which is also a result of its security feature.

Owners can add dynamic watermarks, encrypt with DRM (Digital Right Management), set restricted use and expiry on PDF documents to protect their significant content from editing, forging, copying and other reproducing tricks.

What is ePub?

EPUB is an ebook file format displayed with the “.epub” file extension. The full term of ePub is Electronic Publication, or e-publishing files.

The most significant feature of ePub is its flexibility. Readers can read ebooks in ePub format with most of the hardware readers. They can also reflow them and change their typography, such as font family, font size, spacing and pagination.

Like PDFs, ePub materials support XHTML (Extensible HyperText Markup Language) as well, which means it can carry contents, images and other supporting files. Also, owners can use the DRM to protect their ePub data.

Critical Differences Between PDF and ePub

#1 Content Reflow

PDFs are in a fixed format and can be hardly changed, so it is not reflowable in many devices. This is to say, you cannot change its font size, typeface, pagination and text direction to match your display size.

You can only zoom in or out to see texts and image details. Because of its stable feature, you’ll either need a great PDF reader software or open it on a same-size (usually A4-size) device, such as BOOX Max Lumi or Sony DPT-1, to achieve a comfortable reading experience.

Compared to PDF, ePub can fit perfectly into different-size screens and render the best readability after rearrangements to its presentation.

#2 Creating and Editing

Creating a PDF needs Adobe Acrobat’s PDF creator, while making an epub file requires you to acquire basic knowledge of coding or turn to some software for help.

It sounds that creating an epub is more complicated than PDFs. However, when it comes to editing, you may find it easier on e-publishing files if you are familiar with coding. You just need to modify their codes to change their content or layout.

If you want to edit the content of PDFs, you’ll need an Adobe subscription. But it doesn’t mean that you cannot annotate, ensign or highlight PDFs. You can do so with the help of some professional software.

#3 Rich Media

As ePub is used by many ebook publishers to present books, it is more capable than PDF in terms of displaying multimedia, such as videos, audios and other interactive content. Therefore, it can create a more varied reading experience for readers to help them comprehend the book content.

#4 Reading Device

PDF files can be read on many tablets and computers with the help of PDF reading software. Some ebook readers can also handle PDF files, including iPad, Kindle, Nook, Kobo, BOOX and Sony.

As for ePub, it is made for displaying ebooks, so most eReaders except for Kindle can support this format of digital books. You can also use some applications to open ePub files on laptops and tablets.

Is ePub or PDF Better? Best Book Format?

Both ePub and PDF can be used to show digital documents. Which is better for books? It depends.

As we’ve mentioned before, ePub is made for digital books. Many ebook publishers employ the electronic publication format to render rich reading experiences for readers. So you can find most of the ebooks are published with the “.epub” extension, especially young adult fiction, romance, light novels, and short stories.

PDFs are fixed, stable content, so a lot of articles, academic materials and non-fiction will use Portable Document Format to protect their content from reproduction. Also, most of the scanned digital materials are reserved in PDF.

Read Both ePub and PDF Comfortably with One Device

For users who read both ePub and PDF, reading documents without changing software on one device can be more convenient.
