What to expect

  • The book becomes standard HTML plus images bundled in a ZIP; e-book navigation is reduced to ordinary links.
  • DRM-protected MOBI files cannot be converted; only DRM-free books work.
  • Styling is approximated in CSS, so fine typographic details from the original may not match exactly.

Frequently asked questions

What is in an HTMLZ file after conversion?
HTMLZ is a ZIP archive holding the book's HTML plus its images and styling. Since MOBI already wraps compressed HTML internally, the text content maps naturally onto standard HTML markup.
Why convert MOBI to HTMLZ?
HTMLZ turns the e-book into ordinary web-standard HTML, which is convenient for editing the text, reusing content, or feeding it into tools that work with HTML rather than e-book containers.
Where can I open HTMLZ output?
Unzip it and the HTML opens in any web browser or HTML editor. E-book software such as Calibre can also read HTMLZ directly.
Is anything lost going from MOBI to HTMLZ?
The readable text and images survive well, but e-book-specific navigation and reader metadata are flattened into plain HTML and CSS. The polished chapter navigation of the original may become simpler linked markup.
