+## Description
+
+Learn how to convert PDF documents to TIFF format in .NET Standard.
+
+## Solution
+
+To convert PDF documents to TIFF images in .NET Standard, follow these steps:
+
+1. Use the [SkiaImageFormatProvider]({%slug radpdfprocessing-formats-and-conversion-image-using-skiaimageformatprovider%}) to export the PDF pages to images.
+2. Utilize the [System.Drawing.Common](https://www.nuget.org/packages/System.Drawing.Common/) library to assemble these images into a multi-page TIFF file.
+
+Here's an example code snippet demonstrating the process:
+
+```csharp
+using System.Diagnostics;
+using System.Drawing;
+using System.Drawing.Imaging;
+using Telerik.Documents.Fixed.FormatProviders.Image.Skia;
+using Telerik.Windows.Documents.Fixed.FormatProviders.Pdf;
+using Telerik.Windows.Documents.Fixed.Model;
+using System.IO;
+
+namespace PdfToTIFFNetCore
+{
+    internal class Program
+    {
+        [STAThread]
+        static void Main(string[] args)
+        {
+            PdfFormatProvider pdfFormatProvider = new PdfFormatProvider();
+            RadFixedDocument fixedDocument = pdfFormatProvider.Import(File.ReadAllBytes("your-pdf-file.pdf"), TimeSpan.FromSeconds(10));
+            SkiaImageFormatProvider imageProvider = new SkiaImageFormatProvider();
+            string exportedFileName = "Exported.tiff";
+            using (FileStream fileStream = new FileStream(exportedFileName, FileMode.Create))
+            {
+                System.Drawing.Imaging.Encoder encoder = System.Drawing.Imaging.Encoder.SaveFlag;
+                ImageCodecInfo codecInfo = GetEncoderInfo("image/tiff");
+                EncoderParameters encoderParams = new EncoderParameters(1);
+                encoderParams.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.MultiFrame);
+
+                Bitmap firstImage = null;
+                bool firstFrame = true;
+
+                foreach (RadFixedPage page in fixedDocument.Pages)
+                {
+                    byte[] resultImage = imageProvider.Export(page, TimeSpan.FromSeconds(10));
+                    using (MemoryStream ms = new MemoryStream(resultImage))
+                    {
+                        using (Bitmap bitmap = new Bitmap(ms))
+                        {
+                            if (firstFrame)
+                            {
+                                firstImage = new Bitmap(bitmap);
+                                firstImage.Save(fileStream, codecInfo, encoderParams);
+                                firstFrame = false;
+                            }
+                            else
+                            {
+                                encoderParams.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.FrameDimensionPage);
+                                firstImage.SaveAdd(bitmap, encoderParams);
+                            }
+                        }
+                    }
+                }
+
+                encoderParams.Param[0] = new EncoderParameter(encoder, (long)EncoderValue.Flush);
+                firstImage.SaveAdd(encoderParams);
+            }
+
+            Process.Start(new ProcessStartInfo() { FileName = exportedFileName, UseShellExecute = true });
+        }
+
+        private static ImageCodecInfo GetEncoderInfo(string mimeType)
+        {
+            ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();
+            foreach (ImageCodecInfo codec in codecs)
+            {
+                if (codec.MimeType == mimeType)
+                {
+                    return codec;
+                }
+            }
+            return null;
+        }
+    }
+}
+```
+
+Replace `"your-pdf-file.pdf"` with the path to your PDF file. This code will create a TIFF file named `Exported.tiff` containing all the pages from the PDF document.
