How is this different from Split PDF?

Extract keeps a list you choose — pages 2, 7 and 11, say. Split cuts on a boundary: a range, the halfway point, or every page.

Do the extracted pages keep their quality?

Yes. Pages are copied whole, with no re-encoding, so nothing degrades.

Yes. Choose separate files and every page you picked becomes its own PDF, named after the page it came from.

Links inside the pages you keep survive. Bookmarks pointing at pages you left behind cannot, and are dropped rather than left broken.

Save chosen pages as a new document, together or as separate files.
