To reorder pages, drag the page tabs into the order that you want.
Tip: You can also right-click a page tab and click Reorder Pages.
If you have used the default page names, such as Page-1, when you reorder the pages, Microsoft Office Visio renumbers the page names to reflect the new order.
In the page tab area, foreground pages always appear to the left and backgrounds to the right.
You cannot reorder background pages. They always appear at the right side of the page tab area in the order in which they were created.

You can’t reorder pages in Visio for the web. But you can edit the diagram in Visio, reorder the pages, save and close the file, and then refresh the Visio for the web diagram.
