FB2 → HTML
Converting a novel from FictionBook (.fb2) to HyperText (.html, .htm, .xhtml, .xml, .mhtml) is a routine step in practice — HTML opens in any browser and embeds easily into a web page. Fortunately FictionBook and HyperText are structurally close, so there is not much to lose. Below we explain in detail how FictionBook becomes HyperText and what to watch out for, and the page ends with a converter that does the job right in your browser — nothing is uploaded, the file never leaves your machine.
What is FB2?
FB2 (FictionBook) is an open e-book format based on XML. Text, metadata and illustrations all live in a single file, with images embedded as Base64, so one file distributes completely and you never end up with the text present but the images missing. Its structure is simpler than EPUB and therefore easier for readers to implement, and it is most popular in Russian-speaking regions. The drawback is that it supports almost no complex CSS, so it suits text-plus-illustration books rather than titles that depend on fine layout. Read the FB2 format guide
| Extensions | .fb2 |
|---|---|
| Typical use | Russian-language e-books; single-file distribution where embedded illustrations and full metadata matter. |
What is HTML?
HTML and XHTML are the structural languages of the web, and XHTML is also what EPUB uses internally to hold its content — so converting between HTML and EPUB is essentially a matter of swapping the shell and how assets are packaged. .mhtml goes further and packs a page together with its images and styles into one file, which suits preserving online pages that may disappear. HTML's strength is that it is universal and opens in any browser; its weakness is that styles and images are usually external links, so shipping one self-contained file means inlining them first.

| Extensions | .html.htm.xhtml.xml.mhtml |
|---|---|
| Typical use | Captured web content, EPUB internal content, and a general intermediate representation for other formats. |
How to convert FB2 to HTML
FB2 is a single XML file with Base64-embedded images. Parsing must handle the XML namespace and <binary> nodes; ignoring them silently drops every image. Base64 also makes the file roughly a third larger than an equivalent EPUB.
Whether images and styles are linked or embedded decides if the result travels as one file. To ship a single file, inline the assets as data URIs or use MHTML; otherwise moving the file breaks the images. Keep semantic tags (h1–h6, p) so a later EPUB conversion still yields a table of contents.
If you still want chapter navigation inside the HTML file, a novel reader such as Tide Reader can split it automatically by recognising explicit chapter-heading lines in the text.
