Converting TIFF to PDF
Converting multi page TIFF to PDF
Multi frame TIFF image can be converted to PDF document using PdfBitmap class. This can be done by accessing each frame of the multi frame TIFF image and rendering it in each page of the PDF document.
The code snippet to illustrate the same is given below.
using Syncfusion.Pdf.Graphics;
using Syncfusion.Pdf;
//Create a PDF document
PdfDocument pdfDocument = new PdfDocument();
//Load multi frame TIFF image
PdfBitmap tiffImage = new PdfBitmap("image.tiff");

//Access each frame and draw into the page
for (int i = 0; i < frameCount; i++)
{
tiffImage.ActiveFrame = i;
//Add a section to the PDF document
PdfSection section = pdfDocument.Sections.Add();
//Set page margins
section.PageSettings.Margins.All = 0;
//Create a PDF unit converter instance
