+# Merge PDF Documents
+
+**RadPdfProcessing** provides support for merging multiple PDF documents into one using the following approaches:
+
+## Using the RadFixedDocument.Merge Method
+
+You can merge PDF documents out-of-the-box with the **Merge** method of [RadFixedDocument]({%slug radpdfprocessing-model-radfixeddocument%}). This method clones the source document and appends it to the current instance of RadFixedDocument:
+
+<snippet id='libraries-pdf-features-merge-documents-with-radfixeddocument'/>
+
+## Using the PdfStreamWriter
+
+An alternative approach is using the [PdfStreamWriter]({%slug radpdfprocessing-formats-and-conversion-pdf-pdfstreamwriter-overview%}) allowing you to merge pages from different PDF documents:
+ 
+<snippet id='libraries-pdf-features-merge-documents-with-pdfstreamwriter'/>
+
+>note The following SDK example is quite useful on this topic as well: [SDK Demo](https://github.com/telerik/document-processing-sdk/tree/master/PdfProcessing/ManipulatePages).
