The Go4Convert has no limitation of file size. This is its most important feature. In addition, it's very fast - perhaps the Go4Convert is the fastest online EPUB converter I've ever used. It uploads faster, converts faster, and operates easier –just select a file and the converter will do the rest. No extra clicking or setting. Just convert in one-click!

The output file of Go4Convert has smaller size than other online converters and it's not specialized for some device. In other words, it doesn't have a very high quality.

Hey Jonny,

There is also the online Epub Generator, where you can copy-paste your text directly online and generate the Epub :

It's a great and easy tool (especially for short text) to generate quickly. The good thing is that (even if it's online) it garantees that text is not kept on any server.

Thanks for your good suggestion, but our this article is focused on "ePub converter", not "ePub generator, so I may not add this tool to the list.

But thank you all the same, and when writing related article, I will consider adding this tool to share with my readers.
