how to convert html to epub?

Question

Can I do this conversion with any programming language or library?

Answer 1

Calibre supports a wide variety of input formats, including HTML, and a wide variety of output formats, including EPUB, but it's not "a programming language or library". Are there specific reasons you desire a programming-based approach rather than a free-standing tool? If so, maybe Python and ebookmaker.py, for example, could help you.

Answer 2

Here's pdf to epub, I know that's not what you're after, but it's a start.

The calibre package may have what you want

Answer 3

I am using the following library from Aspose - http://www.aspose.com/categories/.net-components/aspose.words-for-.net/default.aspx

In just two lines of code I am able to do html to epub conversions. Using this currently in a production system.

Document doc = new Document(_sourceFilePath);

doc.Save(_destinationFilePath, SaveFormat.Epub);
