i am using SharePoint online and was wondering how to allow user to only upload PDF file,IF there any out of the box solution would be great.

There is no OOTB solution to restrict file with specific extension. You can create event receiver and override "ItemAdding" method.In this method,you can check the extension of file. If you want to restrict a specific file you can cancel the event.

You could try below script to list form.

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script type="text/javascript">
    function PreSaveAction() {
        var Check=true;
        $('#idAttachmentsTable').find('tr').each(function () {
            var filepath = $(this).find('span[dir="ltr"]').text();
            if (filepath.indexOf(".pdf")=="-1") {
                Check = false;
                alert("Not PDF"+filepath);                
            }

        })
        return Check;
    }
    </script>
