How to Sanitize PDF

using IronPdf;

try
{
    // Import a PDF document from a file named "sample.pdf".
    // The PdfDocument.FromFile method loads the PDF into a PdfDocument object.
    PdfDocument pdf = PdfDocument.FromFile("sample.pdf");

    // Sanitize the PDF document using a bitmap sanitation method.
    // This method aims to remove malicious content by converting pages to images and then back to a PDF.
    PdfDocument sanitizeWithBitmap = Cleaner.SanitizeWithBitmap(pdf);

    // Sanitize the PDF document using an SVG (Scalable Vector Graphics) sanitation method.
    // This approach aims to preserve vector graphics and text content while removing potentially harmful content.
    PdfDocument sanitizeWithSvg = Cleaner.SanitizeWithSvg(pdf);

    // Export and save the sanitized PDFs to new files.
    // "sanitizeWithBitmap.pdf" will contain the bitmap-sanitized document.
    sanitizeWithBitmap.SaveAs("sanitizeWithBitmap.pdf");
    
    // "sanitizeWithSvg.pdf" will contain the SVG-sanitized document.
    sanitizeWithSvg.SaveAs("sanitizeWithSvg.pdf");

    // Notify the user that the files have been sanitized and saved successfully.
    Console.WriteLine("PDFs have been sanitized and saved successfully.");

    // Handle potential exceptions, such as file not found errors or read/write issues.
    // Provide an informative message to the user about the error that occurred.
