I reversed pages in the PDF and saved. But it opened up in FoxIt and no longer reversed.
You may probably use the Reverse View feature under View menu. As the name hints, this Reverse View is to reverse pages for viewing only. No changes will be saved with the document.
Go to Organize menu, click on Reverse to reverse the page order of the document and save it.
Note:The above solution is only available in Foxit PhantomPDF 9.7 and above. To use this feature, please download a trail version of Foxit PhantomPDF from our website at www.foxitsoftware.com/downloads or purchase it after the expiration of the trial.
