Previously I wrote a tutorial about how to merge two or more PDF files. This tutorial will do the opposite. I will present how to split a PDF with multiple pages into multiple PDFs using the Java iText API from Lowagie. You will be requiring the iText API to run this program and you can download it from www.lowagie.com/iText/

This program will take two parameters as input which are defined inside the main method.

• First parameter is the full path of PDF file that needs to be split.
• Second parameter is the number of pages the each split should have.

For example, if you have a PDF of 15 pages, you might want to split into 4 pages each. There will be total 4 splits. First three splits will have 4 pages each, while the last split will have 3 pages (4+4+4+3=15).

Just summarizing what can be learned from the following program:

• 1. Using iText API to read PDF file
• 2. How to find total number of pages in the PDF
• 3. How to Use PdfCopy and PDFImportedPage features
• 4. PDF Splitting Logic
• 5. How to trigger the PDF file writing using PdfCopy

Previously I wrote a tutorial about how to merge two or more PDF files. This tutorial will do the opposite. I will present how to split a PDF with multiple pages into multiple PDFs using the Java iText API from Lowagie. You will be requiring the iText API to run this program and you can download it from www.lowagie.com/iText/

This program will take two parameters as input which are defined inside the main method.

• First parameter is the full path of PDF file that needs to be split.
• Second parameter is the number of pages the each split should have.

For example, if you have a PDF of 15 pages, you might want to split into 4 pages each. There will be total 4 splits. First three splits will have 4 pages each, while the last split will have 3 pages (4+4+4+3=15).

Just summarizing what can be learned from the following program:

• 1. Using iText API to read PDF file
• 2. How to find total number of pages in the PDF
• 3. How to Use PdfCopy and PDFImportedPage features
• 4. PDF Splitting Logic
• 5. How to trigger the PDF file writing using PdfCopy

Previously I wrote a tutorial about how to merge two or more PDF files. This tutorial will do the opposite. I will present how to split a PDF with multiple pages into multiple PDFs using the Java iText API from Lowagie. You will be requiring the iText API to run this program and you can download it from www.lowagie.com/iText/

This program will take two parameters as input which are defined inside the main method.

• First parameter is the full path of PDF file that needs to be split.
• Second parameter is the number of pages the each split should have.

For example, if you have a PDF of 15 pages, you might want to split into 4 pages each. There will be total 4 splits. First three splits will have 4 pages each, while the last split will have 3 pages (4+4+4+3=15).

Just summarizing what can be learned from the following program:

• 1. Using iText API to read PDF file
• 2. How to find total number of pages in the PDF
• 3. How to Use PdfCopy and PDFImportedPage features
• 4. PDF Splitting Logic
• 5. How to trigger the PDF file writing using PdfCopy
