Understanding FB2 and HTML Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

FictionBook E-Book

application/x-fictionbook+xml

FB2 (FictionBook 2.0) is an XML-based e-book format popular primarily in Russia and Eastern Europe. It stores book content with structured metadata including author information, genre classification, and series data in a single XML file. FB2 separates content structure from presentation, allowing reading applications to apply their own styling while preserving the logical document hierarchy.

Advantages

  • Rich structured metadata including author, genre, series, and annotation
  • Single self-contained XML file with embedded images in base64
  • Strong support in Eastern European and Russian e-reading ecosystems

Limitations

  • Very limited adoption outside of Russia and Eastern Europe
  • Fewer features than EPUB 3 for multimedia and interactive content
  • Not supported by mainstream Western e-readers like Kindle or Kobo

Common Uses

  • Russian-language e-book distribution and libraries
  • Eastern European e-reader devices and applications
  • E-book archiving with comprehensive structured metadata

Target Format

HTML E-Book

text/html

HTML files can function as basic e-books, offering formatted text with headings, images, hyperlinks, and CSS styling viewable in any web browser. Many e-book conversion tools accept HTML as input or produce it as output, since EPUB itself is essentially packaged HTML. Single-file HTML e-books provide a simple way to distribute readable content without requiring specialized e-book software.

Advantages

  • Viewable in any web browser without specialized e-book software
  • Full formatting capabilities with CSS styling and embedded images
  • Natural input and output format for e-book conversion tools

Limitations

  • No e-book-specific features like bookmarks, annotations, or offline library management
  • Single HTML files with embedded images can become very large
  • Not recognized by e-reader devices as a native e-book format

Common Uses

  • Source format for EPUB and other e-book format conversion
  • Online reading of e-book content in web browsers
  • Intermediate format in e-book production pipelines
