<p>HostSalt Image Optimizer connects your WordPress site to the HostSalt IO cloud API to automatically compress and convert images on upload. No server-side libraries required — just install, connect and start saving bandwidth.</p>
<p><strong>Features:</strong></p>
<ul>
<li>Automatic optimization on upload — no manual steps needed</li>
<li>Converts images to WebP or AVIF for maximum compression</li>
<li>Smart format selection — picks whichever format saves more</li>

<p><strong>How it works:</strong></p>
<p>When you upload an image, HostSalt Image Optimizer sends it securely to the HostSalt IO API. The API compresses and converts the image, then returns the optimized version. The original is kept as a backup so you can restore at any time.</p>
<p>A free plan is available with 50 optimizations per month. Paid plans are available for higher volumes.</p>
