To ensure the flipbook can be viewed across all device types and browsers, every page in the PDF is converted to an image.
This image is then scaled and displayed using sophisticated code.
A trade-off to achieve this, is quality.

Where text in a PDF is vector-based and can be zoomed indefinitely, an image is compressed and composed of rasterized pixels.

But - the trade-off ensures that your content can be loaded effortlessly, across all internet connections and device types :)
