eBook Challenges Faced by Publishers, Authors, and Brands in 2025

Several developments were brought about by the World Wide Web Consortium’s (W3C) publication of ePUB 3.3 in 2023, including expanded accessibility features and better compatibility with web technologies.

1. Large-Scale Conversion from PDF to ePUB3

Many publishers and brands have extensive libraries of content in static PDF format. While PDFs are widely used, they are not optimized for today’s demands of interactivity, accessibility, and cross-platform compatibility.

To stay relevant, businesses often need to:

  • Republish in Multiple Languages: Reach global audiences by creating multilingual versions of eBooks.
  • Enhance Accessibility: Add features like read-aloud and adjustable text sizes to cater to readers with different needs.
  • Embed Multimedia: Include videos, audio, animations, and interactive elements to create engaging and dynamic experiences.
  • Ensure Device Compatibility: Adapt content for seamless readability across smartphones, tablets, eReaders, and desktops.

ePUB Accessibility 1.1, integrated with ePUB 3.3, allows businesses to make their eBooks compliant with global accessibility standards, such as the European Accessibility Act.

2. The Growing Demand for Interactivity

Modern readers expect more than just plain text and static images. They want immersive experiences with multimedia integration, real-time interactivity, and tailored content.

Modern digital publishing now revolves around interactive storytelling, which requires the incorporation of audio, video, animations, and interactive quizzes or polls to increase reader involvement.

Publishers must balance cost control and satisfying these needs. Nowadays, digital publishing platforms provide scalable solutions that let artists embed these components without paying a high price, guaranteeing a competitive edge in a saturated industry.

Technologies like augmented reality (AR) are also being used to provide distinctive reading experiences. For example, users can examine 3D models or interactive maps directly inside eBooks.

3. Adapting to Rapid Technological Advancements

The ceaseless fluctuations throughout the digital publishing industry do not come as a surprise to most readers.

New tools and technologies are being developed to improve the reader’s experience. Instead, authors, publishers, and even brands are likely to battle with keeping up with the following advancements:

  • AI-Powered Personalization: Using AI to tailor content recommendations and improve reader engagement.
  • Augmented and Virtual Reality Integration: Creating immersive storytelling experiences through AR and VR elements.
  • Advanced Analytics: Leveraging data to understand reader behavior and improve content strategies.

In keeping with current trends, many more resources must be invested in various systems, human resources, and networking to integrate such technologies into ebook production and distribution channels. Failure to adapt can leave businesses struggling to meet reader expectations and falling behind their more tech-savvy competitors.

Overcoming these challenges in 2025 will be crucial for publishers, authors, and brands to tap into the growing digital readership and maximize their reach in an increasingly globalized and tech-savvy audience.

What is an ePUB3 File?

Unlike a PDF file, an ePUB file is an innovative format that enables reflowable text. Thus, the content format automatically adapts to the screen resolution of the device used.

PDFs tend to be heavier than ePUB files because the latter are stored in a zip file and use HTML to proceed. ePUB3 is the latest version of ePUB, and one of its key advantages is that it enables files to be embedded with videos, audio, and interactive multimedia elements.

Moreover, any content, such as an eBook produced with ePUB3, can be more engaging. This is great news for publishers, businesses, and content creators who aim to deliver high-quality, accessible content.
