How to use it
- Add your files. Drop HTML files on the page or use Choose files. Folders and ZIPs work too.
- Check that EPUB is selected. EPUB is already chosen on this page.
- Adjust options if you need to. Quality, size and other settings appear when the format has them.
- Convert and download. Press Convert; with several files, “Download all” gives you one ZIP.
What happens to your file
The HTML is read in your browser and turned into clean structure (headings, paragraphs, lists, tables, links and pictures), which is then written as EPUB. Fonts, colours and exact page layout are not copied, so the result is tidy and easy to edit.
About HTML and EPUB
HTML: HTML is the format of web pages.
EPUB: EPUB is the standard ebook format, read by Apple Books, Google Play Books, Kobo and most e-readers.
Questions
Is my HTML file uploaded?
No. The conversion runs inside this browser tab, and the EPUB is created on your device. Nothing is sent to a server.
Anything to know about EPUB?
Text, headings, pictures and chapters are kept; the ebook’s own fonts and page styling are not. DRM-protected ebooks cannot be opened.
Can I convert several HTML files at once?
Yes. Drop as many as you like, a folder or a ZIP; “Download all” saves every EPUB in one ZIP.
