Issuu converts PDFs into digital publications that can be shared via links or embedded into websites. Users can edit their publications by customizing the design, using templates, or adding links and multimedia to the pages of their documents. Issuu also provides tools for measuring and monetization of content.

PDFs are an end use and convertibility varies between poor or not at all unless OCR & proofing is done. PDF is for producing paper print, print replica or paper preview. Occasionally online or electronic form submission (but a web page is better). PDFs are not true ebooks. Real ebooks reflow but are paginated so as to give a book reading experience on any screen from 2″ and upwards, with any screen resolution.
I think the Issuu documents only work online or on their own app (iOS and Android) and I suspect it needs an iPad or Android tablet.
I imagine Pearson and similar technical publishers might like it if the DRM is good. I'd avoid this platform even for technical material.
