Smart images optimization and WebP convertation on the fly with <a href="https://optipic.io/en/cdn/" rel="nofollow ugc">OptiPic CDN</a>.
What does OptiPic CDN do when trying to request an image from it:
<ul>
<li>Returns the WebP version of the image, if the browser supports WebP format.</li>
<li>Returns a compressed/optimized version without webp, if the browser does not support WebP.</li>
<li>Makes responsive to mobile screens, if the image is opened from a mobile.</li>
<li>Caches and speeds up loading, reducing the load from your hosting.</li>
</ul>
Convertation to Webp and image compression occurs in the background and does not slow down the opening of images on the browser. 
If the optimized version is not yet ready at the time of the image request, the original version is returned without any processing.
What gets optimization of images on the site:
<ul>
<li>Speeding up the site</li>
<li>Improving SEO</li>
<li>Increasing of conversion</li>
<li>Increasing of Google Pagespeed Insights</li>
</ul>

Looking for a WordPress image optimizer without an API key? Squeeze is a local WebP converter that lets you compress images in WordPress, convert uploads to WebP, and bulk compress your media library without ShortPixel-, Imagify-, or Smush-style monthly caps. Processing runs in your admin browser—unlimited squeezes, full privacy, and no uploads to third-party compression servers.
If you need a webp converter wordpress plugin, a shortpixel alternative without recurring API fees, or an image optimizer without api keys, Squeeze keeps optimization on your server and in your browser instead of a SaaS queue.
Unlike cloud-based plugins, Squeeze:
♾️ No compression limits — squeeze your entire Media Library, not just the first 100–500 images per month. 
☁️ No third-party servers — images never leave your site; processing happens locally in the browser (ideal for GDPR-sensitive and membership sites). 
⚡ Direct WebP conversion — convert JPG/PNG to WebP and replace the original file on disk (no duplicate copies cluttering storage). 
🖼️ Optimize on upload — compress in Gutenberg, GenerateBlocks, and the Voxel theme before files hit the server (Elementor on-upload squeeze is available in <a href="https://pluginarium.com/squeeze/#premium" rel="nofollow ugc">Premium</a>).
The result: smaller files, faster page loads, and lower hosting storage—without SaaS fees or API keys.

<h3>How does Squeeze work?</h3>
