<p>If you want to resize featured images (post thumbnails) on the fly for your posts automatically then this plugin can help you.</p>
<p>To take effect just open a post or page and all featured images in that post will be resized to a normal size.</p>
<p>This plugin can be very useful after a theme install.</p>
<p>It can be an alternative for Regenerate Thumbnails plugin.</p>
<p>I think this plugin is better because you will not need to wait before all images are resized for all different sizes, just for images that are need to resize.</p>
<p>The plugin will keep the original copy of all image files.</p>

This plugin is very useful and time-saving! Works fast and doesn't need any extra steps.

Best alternative to Regenerate Thumbnails

<h4>Optimize your WordPress Media Library</h4>
<p>Automatically optimize your existing WordPress media library images, without lifting a finger. Sirv can automatically copy your media library to Sirv, from where images will be served as highly optimized images across Sirv’s fast, global WordPress CDN (19 worldwide locations).</p>
<p>All these images (and more) can be automatically optimized by Sirv:</p>
<ul>
<li>Media gallery images</li>
<li>Featured images</li>
<li>WooCommerce product & category images</li>
<li>Images added via other plugins or scripts</li>

<p>See the <a href="https://sirv.com/features/" rel="nofollow ugc">complete list of features</a> of Sirv’s fresh new take on media hosting and optimization.</p>
<h3>Take your WooCommerce sales to another level</h3>
<ul>
<li>Optimization & CDN delivery of all your product images</li>

<li>Add image watermarks</li>
<li>Add text captions</li>
<li>Serves your files wherever you need them – websites, apps, feeds, social media, email campaigns</li>
</ul>
<h4>Image zoom</h4>
<p>Sirv loves huge images – it can zoom deep inside them very fast. No matter how big, images load fast, just like zooming on a Google Map. The bigger your images, the more impressive this image zoom is – perfect if you have really high quality images.</p>
<h4>Video streaming</h4>
<p>Any video you upload to Sirv will be converted to different resolution video streams, for instant playback. Every user will receive the most optimal stream for their device, screen and network connection speed.</p>
<h4>3D models (GLB and USDZ)</h4>
<p>Upload your 3D models to Sirv and embed them in your web pages and product galleries. It’s easy and automated with Sirv Media Viewer. No coding needed. It also provides Augmented Reality (AR) automatically.</p>
<h4>360 spin</h4>
<p>Shoppers adore spinning products around to see them from all sides. If you’re selling something online, maybe with WooCommerce, Sirv provides a stunning 360-degree photography experience. Simply upload a set of photos and a 360 spin will be immediately ready to embed in your page. It feels incredible on desktop and mobile alike, especially the big full-screen 360 spin view.</p>

<h4>What our users say</h4>
<blockquote>
<p>★★★★★<br />
  “We’ve halved the load time on mobiles of a site that we had already done quite a bit of work on to get image sizes down.” <a href="https://wordpress.org/support/users/martingfisher/" rel="ugc">@martingfisher</a></p>
<p>★★★★★<br />
  “So far the best CDN plugin for WordPress. Please, never disappear!” <a href="https://wordpress.org/support/users/mavenickster/" rel="ugc">@mavenickster</a></p>
<p>★★★★★<br />
  “I was looking for a CDN fast and easy (no need to code)! Sirv is the best – Just upload your photos to your WordPress library and voilà “roulez jeunesse!!!” (French expression). Very good service!” <a href="https://wordpress.org/support/users/disconance/" rel="ugc">@disconance</a></p>
<p>★★★★★<br />
  “Sirv is fantastic! I have a lot of images on my website, and most of them are large, which resulted in slow site speeds, even with a CDN. What I love about Sirv is that they offer a CDN service, but also dynamically resize images based on the user’s browser/device, and serve the right file type. It has meant HUGE speed improvements on my website.” <a href="https://wordpress.org/support/users/basellen/" rel="ugc">@basellen</a></p>
</blockquote>
<h4>Optimal format (every time)</h4>
<p>Google loves next-gen image formats for SEO, but it’s a pain to convert all your images and keep track of them. Sirv solves that. It automatically delivers images to each user in the most optimal format. Usually that’ll be AVIF or WebP and the filesize is dramatically smaller, so Google will reward you with better search ranking.</p>
<p>Sirv’s intelligence always serves the smallest possible file format to each users’ browser. It is 100% automatic. Plus, images are automatically scaled down to the suitable width/height and they’re lazy loaded, so you’ll really have the best possible image solution for WordPress.</p>
