How to convert HTML to EPUB
- Add your .HTML file - drop it in the box above or click to browse.
- Convert it to .EPUB in a few seconds.
- Download your new .EPUB file.
What to expect
- EPUB is internally XHTML and CSS - converting from HTML is essentially a repackage, which is why the result is reliable for clean, single-document HTML files.
- Complex CSS layout (flexbox, grid, absolute positioning) and JavaScript are not supported by e-readers and will be dropped or ignored during conversion.
- Images referenced via external URLs may not embed correctly; store images locally alongside the
.htmlfile before converting to ensure they appear in the EPUB.
Frequently asked questions
Will my HTML page look the same in the EPUB?
Text, headings, links, and lists transfer well. E-readers reflow text to fit the screen and ignore most layout CSS, so expect font and layout changes rather than missing content.
Can I convert a saved web page to EPUB?
Yes, if the page was saved as a complete, self-contained HTML file. A page saved with 'Webpage, Complete' includes a local images folder that Calibre picks up automatically.
Can I merge multiple HTML files into one EPUB?
Yes - with Pandoc, list all files as input arguments and they are merged into one
.epub. Calibre can also convert multiple files in a single job.Does the converted EPUB work on Kindle?
Newer Kindle devices and the Kindle app support EPUB directly. For older Kindle models, use Calibre to convert the
.epub to MOBI or AZW3.
