Extracting pages means saving the sheets you care about as a standalone file. The original PDF is not trimmed: you get a new document with only what you marked.
Extracting is not deleting
If the goal is a clean PDF without covers or annexes, remove those pages from the document. If the goal is to take only the annex, the chapter or pages 3 and 7 somewhere else, extract. Splitting is for when you want several files at once, not one.
