Extracting is the inverse of deleting: instead of saying what to remove, you say what to keep. It's what you want when someone asks for 'just the signature page' out of a forty-page contract.
Select pages from the thumbnail grid, and download them as a new document. The original is untouched — nothing is modified in place, so there's no risk of losing the full version.
Pages don't have to be consecutive. Pick page 1, page 14 and the last three, and they're written into the new file in document order. This is the operation you want when someone needs the signature page and the schedule out of a long agreement, and emailing them the whole forty-page document would be both rude and, depending on what's in the rest of it, unwise.
