Removing attachment from PDF

[ ]

Aspose.PDF can remove attachments from PDF files. A PDF document’s attachments are held in the Document object’s EmbeddedFiles collection.

To delete all attachments associated with a PDF file:

  1. Call the EmbeddedFiles collection’s Delete method.
  2. Save the updated file using the Document object’s Save method.

The following code snippet shows how to remove attachments from a PDF document.

void WorkingWithAttachments::RemovingAttachment() {

 String _dataDir("C:\\Samples\\");

 // Open document
 auto pdfDocument = new Document(_dataDir + u"DeleteAllAttachments.pdf");

 // Delete all attachments

 // Save updated file
 pdfDocument->Save(_dataDir + u"DeleteAllAttachments_out.pdf");
