A program converting PDFs to flipbooks in standalone format readable on iOS wholly offline?

This question is related to one I asked on Software Recs.

Is there a program that converts a PDF to an e-flipbook in the form of an file that a user can download from a website, save on her iOS tablet, and then click on to open so that she can flip through the document, two pages visible at a time, wholly offline?

None of the following programs seem to allow this, although several are able to do it for Windows or macOS, saving the flipbook in .exe or .app format.

  1. 1stFlip Flipbook Creator
  2. Flip Book Maker for PDF
  3. Flip PDF
  4. PDF to Flipbook
  5. Pub HTML5
  6. FlippingBook Publisher
  7. 3D PageFlip
  8. Flip Creator

(I have asked this question elsewhere for Android.)
