2.zip
Removed-err.zip

PdfDocument pdfDocument = PdfReader.Open("2.pdf", PdfDocumentOpenMode.Modify);
foreach (PdfPage page in pdfDocument.Pages)
{
    PdfResources resurce = page.Resources;
    PdfDictionary xobjects = (PdfDictionary)resurce.Elements["/XObject"];
    foreach (var xobject in xobjects.Elements)
    {
        if (xobject.Key == "\Im2") xobjects.Elements.Remove(xobject.Key);     
    }
}
pdfDocument.Save("2-new.pdf");
pdfDocument.Close();

PDF files that delete images in this way will report an error when opened

You also have to remove all references to "\Im2" from the content stream.

Please use Discussions or the Forum for that sort of questions.
