Hi, Try this code : if (FileUpload1.HasFile) { string extension = System.IO.Path.GetExtension(FileUpload1.FileName); if (extension == ".jpg" ) { FileUpload1.SaveAs( "yourpath" + FileUpload1.FileName); } else { Response.Write( "Only .Jpg allowed" ); } } Reference : https://forums.asp.net/t/1411282.aspx?Fileupload+Control+Allow+only+for+image+files http://www.aspdotnet-suresh.com/2015/10/aspnet-fileupload-validate-file-extension-to-allow-only-images-example-in-csharp-vbnet.html

Try Like below: Using Expression: asp:FileUpload ID = "fuImportImage" runat = "server" /> asp:RegularExpressionValidator ID = "regexValidator" runat = "server" ControlToValidate = "fuImportImage" ErrorMessage = "Only JPEG images are allowed" ValidationExpression = "(.*\.([Jj][Pp][Gg])|.*\.([Jj][Pp][Ee][Gg])$)" > asp:RegularExpressionValidator > Using Accept attribute asp:FileUpload ID = "fileUploader" runat = "server" accept = ".png,.jpg,.jpeg,.gif" /> Using C# string fileExtn = System.IO.Path.GetExtension(FileUpload1.FileName) if (fileExtn == "jpeg" ) { Lbl.text = "File format is correct" ; } else { Lbl.text = "Upload correct file format" ; }
