Digital Publishing Standards

EPUB Packaging (OPF/NCX)

EPUB is not a single file; it is a complex ZIP archive. This tool dynamically builds the required mimetype, content.opf (manifest and metadata), and toc.ncx (navigational mapping) files natively in your browser to ensure strict compliance with e-reader standards.

FictionBook (FB2) XML

For platforms relying on semantic structure rather than HTML/CSS, this tool generates valid FB2 XML schemas. It automatically maps your text into <body>, <section>, and <p> nodes with standard FictionBook header metadata.

Reflowable Layouts

Unlike PDFs which lock text into fixed physical pages, EPUB and FB2 outputs are inherently reflowable. The generated structures allow your e-reader hardware to independently control font family, text size, margins, and dark mode themes dynamically.

Send-to-Kindle Ready

Amazon has retired MOBI and AZW3 for personal document delivery. Modern Kindle hardware relies on EPUB. The EPUBs generated here are formatted to pass seamlessly through the "Send to Kindle" ecosystem.

Semantic Text Mapping

To ensure perfect readability, the converter automatically maps your raw text and basic HTML into strict, semantic paragraph (<p>) and heading (<h1>) nodes, preventing broken layouts or overlapping text on older e-ink devices.

Universal UTF-8 Encoding

Digital manuscripts often contain smart quotes, em-dashes, and international characters. Our compiler enforces strict UTF-8 encoding across all generated XML and HTML files, ensuring symbols render flawlessly without garbled text errors.
