Hello, just put the pdf file into the "Books" section of the iTunes library and synchronize it.

If you have a pdf reader, you can now click on the device name in the left column, select "Application" in the above directory, drop down and find "Enjoy File * * *", and drag the pdf file into the reader.

I hope my answer can help you! If you are satisfied, please adopt it. If you have any questions, you can continue to ask.

You can also send a request to our team, and there will be more professional personnel to solve the problem for you.
