If you need a mobile-optimized version of your digital publication and have a PDF file ready, you can upload it directly as the mobile version.
To create a mobile version of your publication from a PDF file:
Go to My Publications.
Open the collection with the publication that needs to be updated.
Click Edit Settings ⚙.
Go to the Pages tab and click the Upload mobile version button.
Browse the PDF from your device and click the Upload mobile version PDF button.
Click the Save and Close button.
To replace the PDF file click Replace mobile version.
To delete the entire upload and mobile version click Delete entire mobile version.
Important: If the publication has a single-page layout type the PDF for the mobile version can have equal page numbers.
If the publication has the facing-pages layout type, the front and back cover pages are counted as one spread. The rest of the double-spread pages (two pages seen next to each other) are counted as one page for the mobile version.
