What this tool does

Export selected PDF pages as separate PDF files. pdf-lib reads the original PDF and copies pages into new documents. All Pages exports one file per page. Custom ranges use one-based page numbers; each comma-separated entry becomes one output PDF, so 1-3,5 produces a three-page file and a one-page file.

How to use PDF Splitter

  1. Prepare the input. Choose a PDF and wait for its page count.
  2. Run or configure the tool. Choose all pages or enter comma-separated page/range entries.
  3. Check and use the output. Split, download the files and reopen them to inspect page order and content.
