- Download your new .HTMLZ file.
What to expect
- Text, images and inline formatting survive, but the multi-file chapter structure is merged into one HTML document.
- EPUB navigation (table of contents) and container metadata are not carried into the plain HTML.
- EPUB 3 scripting and interactive content are discarded; HTMLZ holds static markup only.
Frequently asked questions
How faithful is the result of an EPUB to HTMLZ conversion?
Because EPUB is already XHTML and CSS inside a ZIP, the text and basic styling carry over cleanly. The main change is that the book's separate chapter files are consolidated into a single HTML document, and some CSS may be simplified in the process.
Why convert EPUB to HTMLZ?
HTMLZ gives you a self-contained, zipped HTML version of the book that is easy to unzip, view in any web browser, or edit as plain markup. It is a convenient format when you want the raw HTML rather than an e-reader container.
Where can I open the resulting HTMLZ file?
HTMLZ is a ZIP archive holding an HTML file plus its images and CSS, so you unzip it and open the HTML in any web browser or text editor. Calibre, which produces the format, can also read it directly.
What is lost when converting EPUB to HTMLZ?
The EPUB's internal structure, such as its spine order and navigation table of contents, is flattened, and EPUB metadata is not preserved as a reader would show it. Any JavaScript or interactive features allowed in EPUB 3 are dropped.
