Square Thumbnails PRO will be available soon. All features currently in the free version will remain free and unrestricted.
Square Thumbnails transforms your images into perfect square thumbnails without cropping or distorting them. Instead of cutting off important parts of your images, the plugin fits them entirely within a square frame, similar to CSS <code>background-size: contain</code>. Ideal for WooCommerce shops, portfolios, and image galleries where consistency is essential, but you don’t want to lose parts of your images.

<li>No Cropping: Preserves the entire image within a square frame</li>
<li>Background Options: Transparent or colored backgrounds (custom or auto-detected)</li>

I’ve successfully implemented the two requested features for Square Thumbnails version 2.3.0:

<li>JPEG Quality Control</li>
</ol>
<ul>
