Upload your PDF, then pick the option that matches what you need:
Split all pages turns every page into its own PDF.
Split by range creates one PDF per range. Enter something like 1-3, 5, 7-9 and you get three files: pages 1 to 3, page 5, and pages 7 to 9.
Extract specific pages lets you click the page numbers you want and keeps them together in a single new PDF.
When your split produces more than one file, pdfCraft bundles them into a single ZIP so you can download everything at once. If it produces just one file, you get a plain PDF.
