Split PDF

pdfMachine can quickly and easily split pages from a PDF. The software also allows you to add pages and combine PDFs.

Split a PDF into many files

    Start with the PDF you wish to split open in pdfMachine.
    This may be one you have just created using pdfMachine or a PDF that you already have. You can open an existing PDF by right-clicking on the PDF in Windows Explorer and selecting "Open with pdfMachine" or by opening pdfMachine from the Start menu and using the Open menu item.
  1. Select Edit from the pdfMachine toolbar
  2. In the thumbnail view, click on the thumbnail of the page you want to be the first page in the new PDF.
  3. Select the File->Split PDF at Current Page menu item.
  4. A new (additional) pdfMachine Viewer will open. There will now be two pdfMachine viewers open with the two parts of the PDF.
  5. On each pdfMachine viewer elect Save As to save the PDF with the required name.

Split a PDF into more than two PDFs

The Split PDF functionality allows you to split or 'explode' a PDF into smaller PDFs. You can split per page or per set number of pages. To split the PDF once, at a particular page refer to the Split PDF at current page function.

Split PDF Dialog

This dialog is invoked from the tools menu option 'split PDF into many files'.

Filename pattern

Use the Filename pattern to name the separate PDFS. This can contain control codes to name the file based on date, time, automatic incrementing numbers and environment varaibles.
The default pattern is '%Y-%m-%d {AUTONUM3}.pdf' which produces files named such as '2018-10-22 001.pdf','2018-10-22 002.pdf' etc.

For details on this, read :  output pattern.

Pages per PDF

Sets how many pages are put into each PDF file. If greater than one, the final PDF may not have the full number of pages.

Auto number start

The starting number for the {AUTONUM} variables in the filename pattern.


N-Up allows you to shrink several pages on to one page. This is a great paper saving feature, or just handy if you want to see several pages side by side. It can also be used for creating booklets.

Once enabled, all future prints to the pdfMachine will have "N-Up" applied. If you are currently viewing a document in the pdfMachine viewer and enable  "N-Up" then the current document will have "N-Up" applied to it.

Number of pages Either 1, 2, 4 or 8 pages can be shrunk onto one page.
New Page Size This is the page size of the resulting page.
Margin Size This controls the distance between pages and the edge of the page.
Border Size Changes the size of the border.
