<p><strong>Image Compressor WebP by htmlrunner</strong> converts JPEG and PNG images in your media library to WebP format, reducing file sizes without any visible quality loss.</p>
<h3>Your Images Never Leave Your Server</h3>
<p>This plugin works entirely within your own hosting environment. No image data is ever transmitted to our servers or any third-party service. Every conversion runs through your server’s native PHP GD or Imagick library — the same tools already installed on virtually every hosting plan.</p>
<p>This means:</p>
<ul>
<li><strong>Complete data privacy</strong> — your images stay on your infrastructure, period.</li>
<li><strong>No API keys or accounts</strong> — there is nothing to sign up for.</li>
<li><strong>No subscription fees</strong> — no usage limits tied to external credits.</li>
<li><strong>Works offline</strong> — no outbound connection is required for processing.</li>
</ul>
<h3>What It Does</h3>
<ul>
<li>Converts JPEG and PNG images to WebP format directly on your server.</li>
<li>Supports bulk conversion — process your entire media library in one go, or select specific images.</li>
<li>Adjustable compression quality via a dedicated settings page, so you control the size-to-quality trade-off.</li>
<li>Replaces original files with the WebP version to reclaim disk space.</li>
<li>No configuration beyond activation is required to get started.</li>
</ul>
