Direct answer

Choose one PDF file in Split PDF. Select “Extract and download”. The tool creates a new PDF containing the selected pages and downloads split-pages.pdf.

Key takeaways

  • The input 1,3,5-7 should select five pages, not seven.
  • Page numbers refer to the PDF page positions, which may differ from printed page labels.
  • A split is not the same as redaction: deleted pages may still exist in the original file you retain.

Common mistakes

  • The browser implementation uses pdf-lib to copy selected pages into a new PDF.
  • Protected or damaged source PDFs can fail.
  • The tool extracts pages; it does not split the entire file into one file per page.
