Page numbering isn't available yet

We've taken this tool offline. An earlier version returned your document with no page numbers added, while reporting that the operation had completed.

This one is straightforward to build properly, and it's near the front of the queue. It'll come back when it actually writes numbers onto your pages.

In the meantime: if the document started life in Word, Google Docs or Pages, adding page numbers there and re-exporting gives a cleaner result than stamping them on afterwards.
