Understanding TXT and FB2 Formats

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

Source Format

Plain Text E-Book

text/plain

Plain text files serve as the simplest possible e-book format, containing only raw text with no formatting, images, or metadata. Despite their limitations, plain text e-books are universally readable on any device and platform, and are commonly used for public domain literature distribution through Project Gutenberg. Text files ensure maximum accessibility and long-term preservation.

Advantages

  • Universally readable on any device, platform, or application
  • Smallest possible file sizes for text content
  • Maximum long-term preservation with no risk of format obsolescence

Limitations

  • No formatting, images, table of contents, or structural elements
  • No metadata for author, title, cover art, or chapters
  • Poor reading experience compared to formatted e-book formats

Common Uses

  • Project Gutenberg public domain literature distribution
  • Minimalist e-reading on resource-constrained devices
  • E-book format conversion source material

Target 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
