3D FlipBook - Hello, I need a flipbook for our wordpress site to publish testimonials like that, but I do not understand if the plugin can

Hello, I need a flipbook for our wordpress site to publish testimonials like that, but I do not understand if the plugin can only create books from images and PDF’s ? because we dont have any knowledge of creating PDF’s… Is it possible it creates a flipbook from post or pages we have already on our website as testimonials? or is there any other easier way trough wordpress only without having to use other tools? Thank you
