This is where modern EPUB to PDF converters, especially AI-powered ones, make a real difference.

With today’s AI technology, eBook converters don’t just change file formats; they ensure your EPUB files retain their layout, structure, and readability across devices. Many tools can now convert EPUB to PDF with higher accuracy, handle batch processing, and even summarize complex eBooks automatically.

In this guide, we highlight the top 6 eBook converters, including advanced AI tools designed to simplify the conversion process and enhance your reading workflow.

More Than Converter: Summarize EPUB to PDF with AI

You might be in a situation where you have to read multiple eBooks to work on your research, which can be quite time-consuming. Instead of changing EPUB to PDF format, you can summarize eBooks into mind maps to get a quick understanding. Mapify is an AI tool to help you summarize complex links and concepts in a book into visual mind maps and convert them into PDFs.

You can also customize the details of the mind maps, like color, text, or chapters, by chatting with AI or manually editing. Multiple language translation is also available in Mapify. What's more, it supports other types of content AI summarization, including YouTube videos, PDFs, images, audio files, webpages, and research papers.
