HTML to FICTIONBOOK conversion is the process of transforming web-based HTML documents into the FB2 (FictionBook) e-book format, preserving structure such as headings, paragraphs, images and metadata while producing a valid XML-based FB2 file. This conversion adapts HTML content (including inline CSS and common semantic tags) into the hierarchical FB2 schema used by many e-readers and library software.

HTML files typically use the MIME type text/html and are rendered by web browsers to display web pages.

HTML is a widely used markup language primarily designed for web pages, supporting diverse multimedia and scripting. FICTIONBOOK (FB2) is a specialized ebook format focused on structured text and metadata, optimized for electronic reading devices. While HTML offers flexibility for web content, FB2 provides a cleaner, standardized format ideal for ebooks.
Keep individual HTML files under 50–100 MB for fastest uploads and processing; large single files with many images may slow conversion.
To preserve layout and images, include all linked assets (images/CSS) in the same upload or use a ZIP archive; inline images (base64) also work but increase file size.
For consistent text encoding, declare or convert your HTML to UTF-8 before conversion to avoid character corruption in the FB2 XML.
Batch conversions are supported via ZIP uploads but expect higher memory/time usage for large batches; split extremely large collections into multiple jobs.
