Hello,

I am brand new here on the forum: So at first, have a nice day everyone.

And I just finished writing my very first eBook. In Apple Pages version 13, OS Monterey. Pages can create the format "Epub" version 3.2. And that also looks top to the readers on the Mac, iPad and iPhone. The eBook consists of text, links to web pages, images and a TOC. So nothing really out of the ordinary.

Unfortunately, I cannot upload this "Epub" to Epubli. They only allow a version up to a maximum of 2.0.

To downgrade I have found nothing after a really long search. I tried to export from Pages to Word and PDF and then create a file with Calibre, because even there the conversion from 3.2 to 2 is not possible. Unfortunately, this file produces many errors when checking in the upload and has the version 2.0.1, which is also criticized again, since probably only up to version 2.0 is supported.

Sigil was recommended to me by the support, which makes a good impression at first. Unfortunately I can't open older "Epubs" in Sigil, because it says,

Cannot read file /Path to/Book.epub:
file to open is a directory.

Which is very strange. Because it is a valid "epub".

Why do I want to open it? I am trying to find out what is the difference in structure from version 2 to version 3. And then I would do all that even manually myself. I can handle HTML, CSS and XML very well.

But before I start working in the completely wrong direction again. As an experienced user, how would you proceed step by step?

Best regards, Bruno
