Manipulate PDF files with various operations

Actions10

Overview

The "Split PDF" operation of this node allows you to split a PDF file into smaller PDFs by extracting specified pages into a new PDF document. This is useful when you want to isolate certain pages from a large PDF for separate processing, sharing, or archiving.

Common scenarios include:

  • Extracting chapters or sections from a large report.
  • Splitting a multi-page invoice into individual invoices.
  • Creating smaller PDFs from a large scanned document for easier distribution.

For example, if you have a 10-page PDF and want to create a new PDF containing only pages 1, 3 to 5, you specify those pages, and the node outputs a new PDF with just those pages.

Properties

Name Meaning
PDF Binary Field Name of the binary field containing the PDF file to be split.
Pages Pages to extract/split from the PDF. Can be a single page (e.g., "1"), multiple pages or ranges (e.g., "1,3-5"), or "all" for all pages.

Output

The output contains a binary field named output which holds the resulting PDF file after splitting. The binary data includes:

  • data: Base64 encoded PDF content of the extracted pages.
  • fileName: The filename assigned to the output PDF, typically output.pdf.
  • mimeType: Always "application/pdf" indicating the file type.

No JSON fields are added specifically for this operation; the main result is the binary PDF data.

Dependencies

  • Requires the input PDF to be provided as binary data in the specified binary field.
  • Uses the pdf-lib library internally to manipulate PDF files.
  • No external API keys or services are required.
  • The node expects the input binary data to have MIME type application/pdf.

Troubleshooting

  • Error: No binary data found for [field name]
    Ensure that the input item contains binary data under the specified PDF binary field name. The field name must exactly match the one configured in the node.

  • Error: The file must be in PDF format (MIME type: application/pdf). Received: [type]
    Verify that the binary data is indeed a PDF file and has the correct MIME type.

  • Error: Invalid page numbers. Pages must be between 1 and [total pages]
    Check that the pages string specifies valid page numbers within the range of the PDF's total pages. Use formats like "1", "1,3-5", or "all".

  • Error: Pages to extract are required
    Make sure the "Pages" property is set and not empty.
