Hi Syress, 
We appreciate your interest towards Syncfusion products. 
We can split all the pages in a document and it can be stored in a list, We have attached code snippet for saving each page to list as individual PDF document. Please find the code snippet below 
            //Converting loaded file to Byte array 
            byte[] dataBytes = File.ReadAllBytes("loaded.pdf"); 
            //Saving individual pages as  PdfDocument 
            List<PdfDocument> seperatePDF = SeperateAsPDF(dataBytes); 
Code snippet for saving each page to list as individual PdfDocument: 
     public static List<PdfDocument> SeperateAsPDF(byte[] myFile) 
            //Load document. 
            PdfLoadedDocument loadedDocument = new PdfLoadedDocument(myFile); 
            List<PdfDocument> PdfList = new List<PdfDocument>(); 
            for(int i = 0; i < loadedDocument.Pages.Count; i++) 
                PdfDocument doc = new PdfDocument(); 
                doc.ImportPageRange(loadedDocument, i, i); 
            return PdfList; 
Essential PDF also allows to split the pages of an existing PDF document into multiple individual PDF documents. The following code snippet explains the same. 
             //Load document. 
            PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Output.pdf"); 
            //Sets pattern. 
            const string destFilePattern = "Output" + "{0}.pdf"; 
            //Split the pages into separate documents. 
            //close the document 
Please let us know if you need any further information regarding this. 
Surya Kumar.

The Return type should be List<byte[]> . Can you adjust this ?

Hi Syress,  
Thanks for your update.  
Please find the modified code snippet as you requested, please let us know if this satisfies your requirement. 
            //Converting loaded file to Byte array  
            byte[] dataBytes = File.ReadAllBytes("loaded.pdf");  
            //Saving individual pages as  PdfDocument  
            List<byte[]> seperatePDF = SeperateAsPDF(dataBytes);  
Code snippet for saving each page to list as individual Byte array:  
     public static List<byte[]> SeperateAsPDF(byte[] myFile)  
            //Load document.  
            PdfLoadedDocument loadedDocument = new PdfLoadedDocument(myFile);  
            List<PdfDocument> pdfBytes= new List<PdfDocument>();  
            for(int i = 0; i < loadedDocument.Pages.Count; i++)  
                MemoryStream stream = new MemoryStream(); 
                PdfDocument doc = new PdfDocument();  
                doc.ImportPageRange(loadedDocument, i, i);  
            return pdfBytes;
