Need to convert PDF to EPUB? Whether you’re dealing with a single eBook, a batch of documents, or even a scanned PDF, choosing the right tool is essential. After testing several PDF to EPUB converters and consulting industry standards, we’ve identified the best solutions for different needs:

  • For high-quality conversions on PC/Mac, PDNob PDF Editor excels in preserving complex layouts, images, and formatting. As a reliable tool for professional use, it ensures accurate results for documents with intricate structures, offering both affordability and precision.
  • For free and online conversions, Calibre, and Zamzar are convenient options that don’t require installation. These may have file size limits and could cause formatting loss, while privacy could be a concern since files are temporarily stored online. Some services also have usage caps.
  • For mobile conversions, Ebook Converter and PDF to Kindle Converter are useful for on-the-go tasks.

Part 1. PDF vs EPUB Format

When deciding between PDF and EPUB, it’s important to understand their unique advantages. As experts in digital content, we've tested and analyzed both formats based on real-world use cases.

  • PDF is ideal for documents that need to maintain a fixed layout, like manuals, brochures, and legal documents. It ensures that formatting, images, and text remain intact across all devices. However, PDFs are not reflowable, making them less suitable for small screens or eReaders, especially for long-form content.
  • EPUB, on the other hand, is a reflowable format that adapts to screen size, making it perfect for eBooks and articles. It provides a more flexible reading experience, especially on mobile devices and eReaders, but struggles with complex layouts like multi-column text or tables.

Part 2. How to Convert PDF to EPUB without Losing Formatting - PC/Mac

It provides a cost-effective and user-friendly interface for converting standard PDFs into EPUB, making it a great choice for individuals and small businesses. PDNob focuses on offering a straightforward, affordable solution without the complexity of advanced features like OCR or extensive PDF editing.

Part 3. How to Convert PDF to EPUB Online Free

When looking for free online tools to convert PDF to EPUB, the key factors to consider are ease of use, conversion speed, and limitations on file size and features. Below is an in-depth look at Calibre, and Zamzar, all of which provide solutions for converting PDF to EPUB online. Each tool has its strengths and weaknesses, so let’s dive into the details.

1. Calibre

Calibre is one of the most widely used, free, and open-source applications for converting PDF to EPUB. Known for its flexibility and customizable features, Calibre can handle a variety of eBook formats and is particularly appreciated for its ability to adjust layouts, making the resulting EPUB more reflowable and accessible on different devices.

However, while Calibre shines with simple PDFs, users may face formatting issues when converting more complex documents.

Real-World Experience:

When I tested Calibre with a novel (a simple text-based PDF), the conversion was fast and the EPUB format was clean, with adjustable text size and perfect readability on a Kindle. However, when I tried converting a marketing brochure with multiple images, the images didn’t translate well into the EPUB format, and the layout was misaligned, making the document difficult to read.

2. Zamzar

Zamzar is an online file conversion tool known for its simplicity and speed, especially for converting text-heavy PDFs to EPUB format. It supports a wide range of file formats, making it versatile for many different tasks beyond PDF to EPUB.

However, Zamzar's performance with complex PDFs (including those with images, tables, or multiple columns) can lead to quality loss and formatting issues.

Real-World Experience:

I tested Zamzar with various PDF files, ranging from text-heavy novels to business reports with images, tables, and multiple columns. For simple documents, Zamzar performed well—converting text-heavy files into clean, readable EPUBs quickly. However, when working with more complex PDFs, such as technical manuals and research papers, the output was often misaligned, with broken formatting and missing images.

Steps to Convert PDF to EPUB Online via Zamzar

  • Navigate to the Zamzar PDF to EPUB converter: by visiting the Zamzar website.

Part 4. How to Convert PDF to EPUB on iPhone/Android

When it comes to converting PDFs to EPUB on mobile devices, users often seek a quick, portable solution. For iPhone and Android users, Ebook Converter and PDF to Kindle Converter are two viable options.

1. Ebook Converter

Ebook Converter is a dedicated mobile tool for converting PDFs into various eBook formats, including EPUB. Its simplicity makes it an excellent choice for quick conversions on the go. The app is free and works well for basic PDFs. However, it may face difficulties with more complex files, especially those containing images or multi-column text. The app is primarily aimed at casual users who need a quick fix for their reading needs.

Real-World Experience:

I tested Ebook Converter on my iPhone with a few text-heavy PDFs (such as a novel and an article). The conversion process was seamless and quick, with minimal effort needed to get from PDF to EPUB. For basic PDFs, the output was satisfactory—clean text that reflowed easily on my e-reader.

2. PDF to Kindle converter

PDF to Kindle Converter is another useful tool for mobile users, but it is specifically designed for converting PDFs to Kindle’s proprietary format (MOBI or AZW3). Although it’s excellent for Kindle users, it’s not an ideal solution for EPUB lovers. Since EPUB is an open-standard format supported by most eBook readers, the app’s conversion to Kindle format limits its flexibility for other devices. Users who prefer EPUB will need to perform additional steps to convert it from MOBI to EPUB.

book icon
Real-World Experience:

I also tested PDF to Kindle Converter using both PDFs and EPUB files on my Android phone. The conversion process was very simple: just upload the PDF, and it converts to a Kindle-compatible format (MOBI/AZW3). This worked fine for simple PDFs and was especially convenient when I needed to read technical documents on my Kindle device.

Steps to Convert PDF to EPUB on Android via PDF to Kindle Converter

  • Download a converter app: Install an app from the Google Play Store that can convert PDF to EPUB, such as Ebook Converter.
  • Open the converter app and select the PDF: Choose the PDF file you want to convert from your Android device.
  • Select EPUB as the output format: Set the conversion to output an EPUB file.
  • Start the conversion: Run the conversion process through the app.
  • Share the converted EPUB file: Once converted, use the app's share function to send the EPUB file to your Kindle.

👍 Best For

Kindle users who need a fast, reliable tool for converting PDFs to Kindle’s format. Ideal if you’re using a Kindle device and prefer reading PDFs on it.

👎 Not Suitable For

  • Limited to Kindle Formats: The output is in MOBI or AZW3, so it’s not suitable for users who want EPUB files.
  • Poor Formatting for Complex PDFs: PDFs with images, tables, and multiple columns don’t convert well and may need additional manual adjustments.
  • No Direct EPUB Conversion: If you need EPUB files, you’ll need to use a second tool (like Calibre) to convert the MOBI or AZW3 files.
