Question [PDF to EPUB] Prevent Calibre from appending "Document Outline"?
Hello,

Surprisingly, searching this section for "Document Outline" in titles returned no hit

When converting a PDF into EPUB, Calibre appends an annoying "Document Outline" section.

Is there a way to tell it not to?

Code:
"C:\Program Files\Calibre2\ebook-convert.exe" "001.pdf" "001.epub" --enable-heuristics --no-default-epub-cover --authors "John Doe" --title "Some great book"
Thank you.

That's because calibre does not append any such section. Indeed the string 'document outline' is not even present in calibre's source code.

It's something already in some of your PDFs.

It's not in the PDF as far as displayed in SumatraPDF. It's only visible in the EPUB when I run this command to turn the PDF into EPUB:

Code:
"C:\Program Files\Calibre2\ebook-convert.exe" "003.pdf" "003.epub" --enable-heuristics --no-default-epub-cover --authors "Some author" --title "Some book"
FWIW, the PDF contains a bookmarks section.

--
Edit: Must first remove the bookmarks from the input PDF:

Code:
cpdf -remove-bookmarks 003.pdf -o 003.NO.BOOKMARKS.pdf

"C:\Program Files\Calibre2\ebook-convert.exe" "003.NO.BOOKMARKS.pdf" "003.epub" --enable-heuristics --no-default-epub-cover --authors "Some author" --title "Some book"
…
Parsing all content...
Generating default TOC from spine...
…
This EPUB file has no Table of Contents. Creating a default TOC
EPUB output written to c:\003.epub
Output saved to   c:\003.epub

Loads of things are in PDFs that are not displayed in viewers.
