Split a PDF into Multiple PDFs

---

Split a PDF document into multiple PDFs using the pdf endpoint.

---

Use the pdf endpoint to split a PDF into multiple PDFs. In this example you start with a nine-page document and then extract pages 1-3 to form a new PDF and then extract pages 6-7 to form a second PDF. To accomplish splitting a PDF, call the PDF endpoint twice using the same document but different JSON instructions. The first call to the endpoint creates a new PDF from pages 1-3 while the second call to the endpoint creates a new PDF from pages 6-7. The following example illustrates.

Calling Endpoint Directly

The following JSON instructions documents illustrate splitting a PDF into two PDFs. It calls the pdf endpoint twice. The first call uses the following instructions JSON and selects pages 1, 2, and 3.

{
  "author": "CeteSoftware",
  "creator": "DynamicPDF Cloud Api",
  "inputs": [
    {
      "type": "pdf",
      "resourceName": "pdfnumberedinput.pdf",
	  "startPage": 1,
	  "pageCount": 3
    }
  ]
}

The second pdf call selects pages 6 and 7 when creating the new PDF.

{
  "author": "CeteSoftware",
  "creator": "DynamicPDF Cloud Api",
  "inputs": [
	{
      "type": "pdf",
      "resourceName": "pdfnumberedinput.pdf",
	  "startPage": 6,
	  "pageCount": 2
    }
  ]
}

curl --location 'https://api.dpdf.io/v1.0/pdf'
--header 'Authorization: Bearer DP--api-key--
--form 'Instructions=@C:/temp/solutions/delete-pages/instructions-one.json'
--form 'Resource=@C:/temp/solutions/delete-pages/pagenumberedinput.pdf'

Calling Endpoint Using Client Library

The following JSON instructions document illustrates deleting pages from a PDF using the six different client libraries.

C# (.NET)

public static void Run(string apiKey, string basePath, string outputPath)
{
    SplitPdfs.Split(apiKey, basePath, outputPath, 1, 3, "split-one.pdf");
    SplitPdfs.Split(apiKey, basePath, outputPath, 6, 2, "split-two.pdf");
}

static void Split(string apiKey, string basePath, string outputPath, int startPage, int pageCount, string outputFile)
{
    Pdf pdf = new Pdf();
    PdfInput input = pdf.AddPdf(new PdfResource(basePath + "pdfnumberedinput.pdf"));
    input.StartPage = startPage;
    input.PageCount = pageCount;

    pdf.ApiKey = apiKey;
    PdfResponse response = pdf.Process();

    File.WriteAllBytes(outputPath + "/" + outputFile, response.Content);
}

Java

    var pdf = new Pdf();	
    pdf.apiKey =  apikey;
        
    var pdf2 = new Pdf();
    pdf2.apiKey = apikey;

    SplitPdf.Split(pdf, 1, 3, "./resources/split-pdf/split-one.pdf")
    SplitPdf.Split(pdf, 6, 2, "./resources/split-pdf/split-two.pdf");
}

static async Split(pdf, startPage, pageCount, outFile) {
    var pdfInput = pdf.addPdf(new PdfResource("./resources/split-pdf/pdfnumberedinput.pdf"));
    pdfInput.startPage = startPage;
    pdfInput.pageCount = pageCount;

    var res = await pdf.process();
        
    if (res.isSuccessful) {
        var outStream = fs.createWriteStream(outFile);
        outStream.write(res.content);
        outStream.close();
    } else {
        console.log(res.errorJson);
    }

The pdf endpoint takes a JSON instructions document that provides instructions for creating, transforming, merging, and formatting inputs into a combined PDF. Refer to documentation on the instructions schema for information on how to use the pdf endpoint.
