Extracting pages saves a chosen set of pages from a PDF as one new document. You pick the pages or a range and export a fresh PDF, leaving the original unchanged — all locally in your browser.

Yes. Choose individual pages, such as 1, 4, and 7-9, where the range control supports it.
No. It creates a new PDF and leaves the source untouched.
