    Dim strTime As String
    Dim strPath As String
    Dim oDoc As Document
    
    strPath = ActiveDocument.Path & Application.PathSeparator
     strTime = Format(Now, "yyyy-mm-dd hh-mm")
    Set oDoc = Documents.Add 'create a new doc and asign it to oDoc variable
    'write some text in the new doc  reffering to it using oDoc variable
    oDoc.Range.InsertBefore "Visit https://www.automateexcel.com/vba-code-library"
    oDoc.SaveAs FileName:=strPath & strTime, FileFormat:=wdFormatFilteredHTML

Sub MacroSaveAsPDF()
'macro saves pdf either in the same folder where active doc is or in documents folder if file is not yet saved
'
    Dim strPath As String
    Dim strPDFname As String

    strPDFname = InputBox("Enter name for PDF", "File Name", "example")
    If strPDFname = "" Then 'user deleted text from inputbox, add default name
        strPDFname = "example"
    End If
    strPath = ActiveDocument.Path
    If strPath = "" Then    'doc is not saved yet
        strPath = Options.DefaultFilePath(wdDocumentsPath) & Application.PathSeparator
    Else
        'just add \ at the end
        strPath = strPath & Application.PathSeparator
    End If
    ActiveDocument.ExportAsFixedFormat OutputFileName:= _
                                       strPath & strPDFname & ".pdf", _
                                       ExportFormat:=wdExportFormatPDF, _
                                       OpenAfterExport:=False, _
                                       OptimizeFor:=wdExportOptimizeForPrint, _
                                       Range:=wdExportAllDocument, _

End Sub

 

This function will also Save any word document as a PDF:

Sub MacroSaveAsPDFwParameters(Optional strPath As String, Optional strFilename As String)

'strPath, if passed, must include path separator ["\"]

    If strFilename = "" Then
        strFilename = ActiveDocument.Name
    End If
    'extract just file name without extension
    If InStr(1, strFilename, ".") > 0 Then
        strFilename = Left$(strFilename, InStrRev(strFilename, ".") - 1)
    End If


    If strPath = "" Then
        If ActiveDocument.Path = "" Then    'doc is not saved yet, we will use default path
            strPath = Options.DefaultFilePath(wdDocumentsPath) & Application.PathSeparator
        Else    ' use path of active doc
            strPath = Options.DefaultFilePath(wdDocumentsPath) & Application.PathSeparator
        End If
    End If
    On Error GoTo EXITHERE

                                       strPath & strFilename & ".pdf", _
                                       ExportFormat:=wdExportFormatPDF, _
