Convert PDF to EPUB without Losing Formatting
With the popularity of digital reading, PDF has become widely used due to its portability and high shareability. However, for those who like to read long-content books on electronic devices and achieve paperless reading at any time, EPUB is a better choice than PDF.
In this article, we provide you a detailed guide on how to convert PDF to EPUB easily and introduce you tips on how to effectively preserve the original format of PDF during the conversion process. Let’s take a look!
First of all, the first method that can highly preserve the original document format is to perform manual conversion. This method requires the combined use of PDFgear, Microsoft Word and Calibre. PDFgear is the best PDF reader and editor that can effectively copy text in PDF without link breaks. Microsoft Word can effectively modify and restore the format of the original file. Calibre is a commonly used e-book reader that can import files in any format and convert them to EPUB for subsequent reading.
However, this method is only suitable for less complex and plain text PDF documents. For large PDF documents, the latter method is more recommended.

Ensure the PDF is clean, with proper tagging, logical reading order, and actual text (not images of text). This helps the converter understand the structure better.
Apply paragraph and character styles in the original PDF document. Structured PDFs with proper heading levels and lists are easier for converters to interpret.
Some experts recommend first converting the PDF to HTML/XHTML using tools like Calibre, then converting that HTML to EPUB. This two-step process can better preserve formatting.
Professional document format converters can effectively convert documents in multiple formats, such as TXT to PDF, PDF to EPUB, etc. while retaining the original format.
After conversion, open the EPUB file in an editor like Sigil or Calibre’s editor. You can fix formatting issues, tweak CSS styles, and adjust the HTML structure manually.
