How to convert HTML to FB2

  1. Add your HTML web pages

    Drop HTML (HTM) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. FB2 is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the FB2, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The HTML to FB2 converter is part of this page and runs inside your browser. Your web pages are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

HTML to FB2: what to expect

An HTML file depends on a browser and often on separate image and style files. FB2 is a clean, open e-book format that many readers support. HTML is at home in web pages and emails; FB2 is the usual choice for e-books, especially from Russian-language libraries.

Headings become sections; a heading that arrives after a section's text has begun becomes a subtitle instead, because FictionBook does not allow a section to mix text and subsections.

HTML vs FB2

HTML

Web page

HTML is the markup every web page is written in. A saved .html file contains the page's structure and text; its images, styles and scripts usually live in separate files.

FB2

FictionBook e-book

FB2 is an XML e-book format that separates a book's structure from its looks: sections, poems, epigraphs and notes are marked up, and the reader decides the layout. Images sit inside the file as base64 text. It is very common in Russian-language libraries.

Questions

Are my web pages uploaded anywhere?

No. The HTML to FB2 conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting HTML to FB2?

Text is kept. Formatting carries over only as far as FB2 supports it.

Can I convert several HTML files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert HTML to FB2 on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the HTML file, press Convert and save the FB2. There is nothing to install.

Is there a file size limit?

Yes. Files up to 150 MB are accepted; a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
