Convert HTML to EPUB online, free, with the formatting preserved exactly. HTML is the language of web pages, viewable in any browser and easy to publish online. EPUB is the most widely-supported ebook format, reflowable and readable on virtually every e-reader and app. This tool uses a full LibreOffice engine on our secure servers to reproduce fonts, layout, tables and images faithfully — the same technology behind professional office suites — so your EPUB looks just like the original, not a rough approximation.
Convert HTML to EPUB
Upload your HTML file
Drop your HTML web page or click to browse. It is sent securely, converted, and never stored after your download.
Convert to EPUB
Our LibreOffice engine renders the document and exports a clean EPUB ebook, preserving fonts, spacing, tables and images.
Download the EPUB
Save your finished EPUB file instantly. The uploaded copy is deleted automatically once the conversion completes.
Why convert HTML to EPUB?
PDF and image outputs give you a fixed, universal file that looks identical everywhere and cannot be accidentally altered — ideal for sharing, printing, submitting or archiving your HTML content.
How accurate is the conversion?
Very accurate. Because we run the full LibreOffice rendering engine rather than a simple text extractor, complex formatting — multi-column layouts, tables, embedded images, headers and footers, fonts — is reproduced faithfully. This is the same open-source engine trusted by governments and enterprises worldwide.
Common Uses
- Reusing the content of a HTML file in a EPUB workflow without retyping it.
- Sending a document to someone who needs it as EPUB rather than HTML.
- Standardising a batch of mixed files into one consistent EPUB format.
- Meeting a submission or upload requirement that only accepts EPUB.
- Freezing an editable HTML into a fixed EPUB so it can't be changed.

Formatting is preserved
Unlike quick text extractors, this tool uses a real office engine, so fonts, tables, images and layout come through intact rather than as plain unformatted text.

Your file is processed on our secure server and deleted immediately after conversion. We never keep, read or share your documents.
No signup, no watermark
It works in any browser on any device, with nothing to install, no account to create, no watermark and no page limit — completely free.
