Saral PDF Preview lets you attach a PDF file to any WooCommerce product. A configurable button appears on the product page and opens the PDF in a clean, distraction-free lightbox — no download, no print, just a smooth in-browser reading experience powered by PDF.js.
Features
<ul>
<li>Upload a PDF per product via a dedicated meta box in the product editor.</li>
<li>Configurable button text (default: “Preview Book”).</li>
<li>Choose from 7 hook locations on the product page — a live visual diagram shows exactly where the button will appear.</li>
<li>Protected mode (default): the real PDF URL is never exposed to visitors; the file is streamed through a signed REST endpoint.</li>
<li>Public mode: uses the standard WordPress attachment URL.</li>
<li>Zoom in / zoom out controls inside the lightbox.</li>
<li>Keyboard accessible — press Escape to close.</li>
<li>Responsive layout on mobile.</li>
<li>No tracking, no external requests, no upsells.</li>
</ul>

This plugin allows you to create previews of links similar to common social networks when sharing a link.
It works by fetching the link URL and examining either the facebook Open Graph properties or Twitter card tags including any preview image. 
Any title, description or image is stored inside this WordPress’ own database and subsequently used from there to render the Beautiful Link Preview.
Usage:
WordPress versions 5.5 or greater with the Gutenberg block editor enabled will have a Beautiful Link Preview block that can be added directly to posts.
For the Classic editor, or WordPress versions earlier than 5.5, just add the following shortcode to any HTML block in your post or page:
<pre><code>[beautiful_link_preview url="https://zeitwesentech.com"]
</code></pre>
