Here’s how you add a PDF.
- Open the document you want to share. It can be a PDF document, or it can be something like an image document that iOS can convert to a PDF. (The easiest way to find this out is to follow these steps.)
- If a Share button is shown (it’s usually in the top-right of the view), tap it. If it is not shown, you can’t share the document, but if you can share it, the Sharing view appears.
- Look for an option to share with iBooks. If there isn’t one, you can’t share it. But if you can, the document will be added to iBooks as a PDF.
- Tap to open a PDF file you want to add to iBooks. It might be a PDF file on your iCloud Drive, or it might be one saved by one of your apps. It doesn’t matter where it came from.
- If someone sends you a PDF in email (or you send it to yourself), you can just tap the PDF in Mail to add it to your iBooks library.
