What you get

  • Custom ranges such as 1-3, 5, 9-12.
  • One-click split into individual pages.
  • Multiple results are packaged into a single ZIP download.

Tips for better results

  • Splitting never modifies your original file, so it is safe to experiment with different ranges.
  • Need one specific chapter instead of every part? Extract PDF pages is the faster route.
  • If you plan to send the parts by email, split first and compress each part afterwards.

Examples

A 300-page manual that must be shared by section

Split at the section boundaries you note from the table of contents, then rename each resulting file after its section so recipients know what they received.
