# Instant Preview

The Instant Preview feature is a powerful tool for anyone looking to streamline their reading process. With this feature, users can quickly and easily preview articles, videos or podcasts without having to navigate away from their current screen. This allows readers to stay focused on the content at hand and avoid distractions that might come from switching between multiple tabs or windows.

Just click on the bookmark you want to preview on your [Dashboard](/using-reader-mode/dashboard.md) , and select either 

* **Preview** -  bookmark content in distraction-free reader, in PDF reader or as an image 
* **Web** - bookmark content as in their original website

{% hint style="info" %}
Some websites cannot be displayed in this mode as they blocked any external apps/services to view their website externally. 
{% endhint %}
