Why Convert HTML to FB2?

Converting HTML documents to FB2 (FictionBook) format is essential for digital book publishing, ebook distribution, and creating content optimized for e-readers. When you convert HTML to FB2, you're transforming web-based content into a structured ebook format that's specifically designed for fiction literature and widely used in Russia and CIS countries.

FB2 (FictionBook 2.0) is an XML-based ebook format that focuses on content structure rather than presentation. Unlike HTML which is designed for web browsers and emphasizes visual rendering, FB2 is designed for e-readers and emphasizes semantic meaning, metadata, and content organization. This makes FB2 the perfect choice for publishing fiction books, novels, short stories, and literary works where proper structure, author information, and genre classification are important.

Our converter extracts text content from HTML documents, preserves formatting (bold, italic, emphasis), converts images to Base64 encoding, and creates a well-structured FB2 file with proper metadata sections. The resulting FB2 file uses UTF-8 encoding and follows the FictionBook schema, making it compatible with all FB2-supporting e-readers like FBReader, CoolReader, and most hardware e-readers sold in Russia and CIS markets.

FB2 excels in the ebook market for several reasons: it's specifically designed for books (not general documents), supports extensive metadata for cataloging (author, genre, series, keywords), embeds images directly in the file, and creates reflowable text that adapts to different screen sizes and user preferences. This format is the de facto standard for Russian ebook stores and digital libraries, making it essential for reaching Russian-speaking audiences.

Key Benefits of Converting HTML to FB2:

E-reader Optimization: Create ebooks optimized for comfortable reading on e-readers
Russian Market: Reach the huge Russian and CIS ebook market where FB2 is standard
Rich Metadata: Include detailed author, genre, and publication information
Self-Contained: All images embedded in Base64, no external files needed
Reflowable Text: Text adapts to screen size and user font preferences
Structured Content: Proper chapters, sections, and book hierarchy
Small File Size: Compact format, can be compressed further with ZIP

Practical Examples

Example 1: Simple Web Story

Input HTML file (story.html):

<!DOCTYPE html>
<html>

</head>
<body>
  <h1>Chapter 1</h1>
  <p>It was a dark and stormy night...</p>

Frequently Asked Questions (FAQ)

Q: What is FB2 format?

A: FB2 (FictionBook 2.0) is an XML-based ebook format developed in Russia specifically for fiction literature. It focuses on content structure rather than presentation, with rich metadata support and semantic markup for book elements like chapters, epigraphs, poems, and citations.

Q: Can I read FB2 files on my device?

A: Yes! FB2 files can be read on most e-readers and reading apps. Popular readers include FBReader (Android, iOS, Linux, Windows), CoolReader (Windows, Android, Linux), Moon+ Reader (Android), and many others. Most hardware e-readers sold in Russia support FB2 natively.

Q: Will images be included in the FB2 file?

A: Yes! All images from your HTML will be converted to Base64 encoding and embedded directly within the FB2 XML file. This makes the FB2 file completely self-contained with all images included. FB2 primarily supports JPEG and PNG formats.

Q: Is FB2 better than EPUB?

A: It depends on your audience! FB2 is more popular in Russia and CIS countries and has excellent metadata support for fiction. EPUB is more widely used internationally. FB2 files are simpler and smaller. Choose FB2 for Russian/CIS markets, EPUB for international distribution.

Q: Can I convert HTML with JavaScript to FB2?

A: JavaScript code will be removed during conversion, as FB2 is a static ebook format without support for scripting or interactivity. Only the text content, structure, and formatting of your HTML will be converted to FB2 format.

Q: How is metadata handled?

A: The converter extracts metadata from HTML meta tags (title, author, description) and creates FB2 metadata sections (title-info, document-info, publish-info). You can edit the FB2 file after conversion to add more detailed metadata like genres, series, and detailed author information.

Q: Is the conversion free?

Q: Can I edit the FB2 file after conversion?

A: Absolutely! FB2 is plain XML text and can be edited with any text editor or specialized FB2 editors. For better experience, use XML editors like VS Code (with XML extension), Oxygen XML Editor, or dedicated FB2 editors like Fiction Book Editor.
