PDF Split

Breaks one PDF into several parts. You can extract a single page, split into equal chunks, or pull out a specific page range as a new file.

What it does

Use this to pull page 1 out of a 300-page report, split a 500-page book into 50-page chapters, or extract pages 20-40 from a merged PDF as a standalone file.

How to use

  1. Drag the PDF in or click Select Source PDF. The file's page count and size appear once loaded.
  2. Pick a Split Mode (see below).
  3. Enter the page numbers.
  4. Set an Output Prefix for the new filenames (defaults to the source name).
  5. Click Run.

Split modes

ModeWhat it does
Extract Single PageSaves the page you specify as a new standalone PDF.
Split Every X PagesBreaks the document into equal-sized chunks. A 100-page PDF with 25 = 4 files.
Extract Page RangeSaves the range you specify as a single new PDF.

Fields per mode

  • Extract Single Page: Only "Target Page" is shown. Type which page to extract.
  • Split Every X Pages: "Start", "End" and "Pages per File" are shown. Choose the source range to split and how many pages per chunk.
  • Extract Page Range: Type "Start" and "End". That whole range becomes one new file.

Examples

Pull out the cover page: Add the PDF, pick "Extract Single Page", Target Page 1, run. You get report_1.pdf.

Split a book into 50-page chunks: Add the PDF, pick "Split Every X Pages", Start 1, End 500, Pages per File 50. You get 10 files.

Extract an appendix from a contract: Add the PDF, pick "Extract Page Range", Start 45, End 67. You get one contract_45-67.pdf.

Get two ranges out of one file: Extract the first range (1-30), come back and extract the second (31-60). You get two files.

Watch out

  • This tool takes one file at a time, no batch mode. Repeat for more PDFs.
  • Page numbers start at 1.
  • Files over 500 MB show a warning about possible slowdown.
  • Encrypted PDFs show a warning on load. Unlock them with PDF Encrypt first.
  • Invalid filename characters (/ \ : * ? " < > |) in the prefix are auto-replaced with _.
