PDF page numbers are out of order

Yes someone answered my question and helped me fix the problem.

You were given two solutions above.

When I open the pdf  the first page I see is 103 - the last page of a screenplay I wrote. I need the pdf to start with page 1 as I want to send it to a company in LA ... They won't read it unless it starts on page 1 actually the cover page first then1,2,3 etc up to page 103 as last page. I hope this makes sense.

You can use this free tool I've created to do it with a single click:
