What is the Native PDF Viewer?
When you add PDF content to your Hub, the default way to present it is with Flipbooks. Flipbooks have several advantages over standard PDFs, but sometimes you might prefer to present your PDF content more traditionally — just as normal PDFs, in other words. In these situations, you can use the Native PDF Viewer option.
The Native PDF Viewer is exactly what it sounds like: a viewer app that displays PDFs within a user's browser, similar to the experience you'd get in a traditional desktop PDF viewer like Adobe Reader.
PDF.js has several advantages:
- It's a full-featured PDF viewer that displays PDFs directly within a browser, so visitors can consume your PDF content without needing to download the PDF file and view it in an external app;
- It's website-hosted, so it runs automatically — visitors don't need to download or install separate PDF viewer software;
- It's compliant with web standards, so it works in almost any browser.
As a result, if you choose to display the PDF content on your Hub just as standard PDFs, the Native Flipbook Viewer ensures that the experience for your visitors still remains seamless and keeps them in the Hub.
