This technical tip shows how to Add, Delete & Get Attachment in a PDF Document using Aspose.Pdf for Java. In order to add attachment in a PDF document, you need to create a FileSpecification object with the file, which needs to be added, and the file description. After that the FileSpecification object can be added to EmbeddedFiles collection of Document object using add(..) method of EmbeddedFiles collection. The attachments of the PDF document can found in the EmbeddedFiles collection of the Document object. In order to delete all the attachments, you only need to call the delete(..) method of the EmbeddedFiles collection and then save the updated file using save method of the Document object.

Add attachment in a PDF document.
//open document

com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("input.pdf");

//setup new file to be added as attachment

com.aspose.pdf.FileSpecification fileSpecification = new com.aspose.pdf.FileSpecification("sample.txt", "Sample text file");

//add attachment to document's attachment collection


// Save updated document containing table object"output.pdf");

Delete all the attachments from the PDF document.
//open document

com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("input.pdf");

//delete all attachments


//save updated file"output.pdf");

Get an individual attachment from the PDF document.
//open document

com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("input.pdf");

//get particular embedded file

com.aspose.pdf.FileSpecification fileSpecification = pdfDocument.getEmbeddedFiles().get_Item(1);

//get the file properties

System.out.printf("Name: - " + fileSpecification.getName());

System.out.printf("\nDescription: - " + fileSpecification.getDescription());

System.out.printf("\nMime Type: - " + fileSpecification.getMIMEType());

// get attachment form PDF file

try {

    InputStream input = fileSpecification.getContents();

    File file = new File(fileSpecification.getName());

    // create path for file from pdf


    // create and extract file from pdf output = new, true);

    byte[] buffer = new byte[4096];

    int n = 0;

    while (-1 != (n =

    output.write(buffer, 0, n);

    // close InputStream object



} catch (IOException e) {



// close Document object
