Improve the Quality of ePub eBooks with Sigil

Here’s how you could with the free program Sigil.

eBooks are increasingly popular with the rise of eBook readers and reading apps on mobile devices.

As usual, only install if you’re comfortable testing pre-release software.

Getting Started

Download Sigil (link below), making sure to grab the correct version for your machine.

execute the installer, and select your preferred setup language when prompted.

After a moment the installer will appear; setup as normal.

Launch Sigil when it’s finished installing.

Edit Your ePub eBooks

Now you’re ready to edit your ePub books.

Click Open and browse to the file you want to edit.

Or you might choose to view it in Code View and edit the actual HTML directly.

Sigil can easily convert these files to the more useful ePub format.

Note that Sigil may take several moments opening the book, and may even become unresponsive while analyzing it.

Now you might edit your eBook, split it into chapters, or just save it as is.

Either way, check that to select Save as to back up your book as ePub format.

Conclusion

As mentioned before, Sigil seems to run slow at times, especially when editing large eBooks.
