How to remove hyperlinks from the existing PDF document?

The hyperlinks can be removed from the existing PDF document by removing the URI and document link annotations from the document. Please refer the below code snippet and sample for the same.

C#

// Load the file
PdfLoadedDocument lDoc = new PdfLoadedDocument(@"input.pdf");
for (int i = 0; i < lDoc.Pages.Count; i++)
{
    // Get the annotation collection
    PdfAnnotationCollection annotColl = lDoc.Pages[i].Annotations as PdfLoadedAnnotationCollection;
     for (int j = 0; j < annotColl.Count; j++)
    {
        // Get the annotation
        PdfLoadedAnnotation annot = annotColl[j] as PdfLoadedAnnotation;
   
        if (annot is PdfLoadedTextWebLinkAnnotation || annot is PdfLoadedUriAnnotation)
        {
            // Remove the hyperlinks
            annotColl.Remove(annot);
        }
    }
}
 
 
// Save and close the document
lDoc.Save(@"sample.pdf");
lDoc.Close(true);
