What is EPUB
EPUB, short for Electronic Publication, is an open-standard digital book format widely used in eBook publishing. Unlike Word files, EPUB is designed specifically for professional-quality eBooks, offering a flexible structure that allows content to be organized and presented consistently across devices.
As the industry standard for digital publishing, EPUB is widely adopted by authors, publishers, and educational institutions to create digital books that are easy to distribute, maintain, and manage. Its structured format ensures that eBooks meet professional publishing requirements while remaining versatile for a range of devices and platforms.
Why Convert Word to EPUB
Although Word files are commonly used for creating content, they are not structured for professional eBook distribution across multiple devices. Converting Word to EPUB provides multiple benefits:
- Improved Readability Across Devices: EPUB adjusts text flow, making your content readable on small screens like smartphones.
- Professional Presentation: Headings, lists, tables, images, and hyperlinks are preserved and formatted for eReaders.
- Wider Compatibility: EPUB works on Kindle, Nook, Kobo, Apple Books, and other popular eReaders.
- Smaller File Size: EPUB files are lightweight and easier to distribute online.
- Accessibility: Supports features such as text-to-speech and font resizing for readers with visual impairments.
In short, converting Word to EPUB turns a basic document into a reader-friendly, professional-quality eBook that is ready for publishing or distribution.

Method 3: Batch Convert Word to EPUB Automatically with Python
If you need to frequently convert multiple Word documents to EPUB, Python automation is an efficient solution. With Python libraries, you can easily automate batch conversions without the need for manual intervention.
Spire.Doc for Python is a popular library for this task. It allows users to create, manipulate, and convert Word documents into various formats, including EPUB. It offers robust features such as:
- Formatting retention: Ensures your document's structure remains intact.
- Metadata editing: Customize author, title, and other properties.
- Batch processing: Convert multiple files at once, saving time and effort.
This makes Spire.Doc an ideal choice for automating Word to EPUB conversion, especially for businesses or content publishers handling large volumes of documents.
Steps to Batch Convert Word to EPUB with Python:
-
Install Spire.Doc for Python:
To get started, first install the Spire.Doc for Python library using pip. Run the following command:
pip install spire.doc -
Write the Python Script:
Once the library is installed, create a Python script to automate the conversion process. Here's the basic script to convert all Word DOC or DOCX files in a folder to EPUB:
from spire.doc import * import os # Define the input and output directories input_dir = 'path_to_input_files' output_dir = 'path_to_output_files' # Get a list of all Word files in the input directory word_files = [f for f in os.listdir(input_dir) if f.endswith('.docx') or f.endswith('.doc')] # Process each Word file for word_file in word_files: input_file = os.path.join(input_dir, word_file) output_file = os.path.join(output_dir, os.path.splitext(word_file)[0] + '.epub') # Create a Document object doc = Document() # Load the Word document doc.LoadFromFile(input_file) # Save the Word document as EPUB doc.SaveToFile(output_file, FileFormat.EPub) # Close the Document object doc.Close() print("Batch conversion completed successfully!") -
Run the Python Script:
After saving the script, run it from your terminal or IDE. The script will automatically process all Word files in the input folder and save them as EPUB files in the output folder.

Notes:
- You need to modify the input_dir and output_dir variables in this example to point to the appropriate folders on your system.
- You can customize the appearance of the EPUB file during conversion, such as adding a cover image for it. Refer to the official guide: Python: Convert Word to EPUB
Pros:
- Ideal for handling large volumes of documents.
- Fully automated once the script is set up, saving time and effort.
- Can be easily integrated into existing workflows or automated publishing systems.
Cons:
- Requires some programming knowledge to set up the script.
- Not as user-friendly as online converters or desktop software for non-technical users.
- Initial setup might take time to configure and test the automation process.
