Itext PDF remove footer from existing pdf and create new pdf

Question

I have an existing PDF and I need to remove the footer from the PDF on every page.

I fetch all pages from PDF but I am not able to remove the footer from the PDF.

I am using iText version 5.5.0.

Document document = null;
PdfCopy writer = null;
PdfReader reader = new PdfReader("input.pdf");
int n = reader.getNumberOfPages();
outFile = "output.pdf";
document = new Document();
writer = new PdfCopy(document, new FileOutputStream(outFile));
document.open();

for (int j = 0; j < n; j++) {                               
    
    PdfImportedPage page = writer.getImportedPage(reader, j);
    writer.addPage(page);
}

document.close();
writer.close();

How can I remove the footer from this input.pdf file and create a new output.pdf file?

You can use pdfSweep to delete text. See the example https://kb.itextpdf.com/home/it7kb/examples/removing-content-with-pdfsweep

My suggestion is to avoid creating a footer in the first place so that you can avoid recreating the pdf just for removing the footer
