Prerequisite Knowledge

There are typically two types of attachments in PDF, document-level attachments and annotation attachments. The following table lists the differences between them and their representations in Spire.PDF.

Remove Document-Level Attachments from PDF in Python

To obtain all document-level attachments of a PDF document, use the PdfDocument.Attachments property. Then, you can remove all of them using the Clear() method or selectively remove a specific attachment using the RemoveAt() method. The following are the steps to remove document-level attachments from PDF in Python.

• Create a PdfDocument object.
• Load a PDF document using PdfDocument.LoadFromFile() method.
• Get the attachment collection from the document using PdfDocument.Attachments property.
• Remove all attachments using PdfAttachmentCollection.Clear() method. To remove a specific attachment, use PdfAttachmentCollection.RemoveAt() method.
• Save the changes to a different PDF file using PdfDocument.SaveToFile() method.

from spire.pdf import *
from spire.pdf.common import *

# Create a PdfDocument object
doc = PdfDocument()

# Load a PDF file
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Attachments.pdf")

# Get the attachment collection from the document
attachments = doc.Attachments

# Remove all attachments
attachments.Clear()

# Remove a specific attachment
# attachments.RemoveAt(0)

# Save the changes to file
doc.SaveToFile("output/DeleteAttachments.pdf")

# Close the document
doc.Close()

Remove Annotation Attachments from PDF in Python

Annotations are page-based elements, and to retrieve all annotations from a document, you need to iterate through the pages and obtain the annotations from each page. Next, identify if a particular annotation is an attachment annotation, and finally remove it from the annotation collection using the RemoveAt() method.

The following are the steps to remove annotation attachments from PDF in Python.

• Create a PdfDocument object.
• Load a PDF document using PdfDocument.LoadFromFile() method.
• Iterate through the pages in the document
• Get the annotation collection from a specific page through PdfPageBase.AnnotationsWidget property.
• Iterate through the annotations in the collection.
• Determine if a specific annotation is an instance of PdfAttachmentAnnotationWidget.
• Remove the attachment annotation using PdfAnnotationCollection.RemoveAt() method.
• Save the changes to a different PDF file using PdfDocument.SaveToFile() method.

from spire.pdf import *
from spire.pdf.common import *

# Create a PdfDocument object
doc = PdfDocument()

# Load a PDF file
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\AnnotationAttachment.pdf")

# Iterate through the pages in the document
for i in range(doc.Pages.Count):

    # Get annotation collection from a certain page
    annotationCollection = doc.Pages.get_Item(i).AnnotationsWidget

    if annotationCollection.Count > 0:

        # Iterate through the annotation in the collection
        for j in range(annotationCollection.Count):

            # Get a specific annotation
            annotation = annotationCollection.get_Item(j)

            # Determine if it is an attachment annotation
            if isinstance(annotation, PdfAttachmentAnnotationWidget):

                # Remove the annotation
                annotationCollection.RemoveAt(j)

# Save the changes to file
doc.SaveToFile("output/DeleteAnnotationAttachment.pdf")

# Close the document
doc.Close()
