SPINX Digital

<p>Convert JPEG, PNG & GIF to WebP and bulk-optimize your Media Library entirely on your own server. No external services. No data sent. No quotas.</p>
<h3>🚀 Local-First WebP Conversion For WordPress</h3>
<p><strong>SPINX Digital Image Converter</strong> generates lightweight WebP versions of your JPEG, PNG, and GIF uploads — including every WordPress-generated thumbnail size — so your pages load faster and your images stay lighter.</p>
<p>Unlike cloud-based optimizers, <strong>all processing happens on your own server</strong> using PHP’s GD or ImageMagick extension. Nothing is uploaded to a third party, no account is required, and there are <strong>no monthly limits or quotas</strong>. Your images never leave your hosting environment.</p>
<p>It’s built for site owners who want faster image delivery, a safe and reversible workflow, and a clear, honest view of exactly what was converted, skipped, restored, or failed — all from a single dashboard.</p>
<h3>✨ Why Choose SPINX Digital Image Converter?</h3>

<p><strong>One-Click Restore</strong> — Switch delivery back to your original media files and remove generated WebP files whenever you need to.</p>
</li>
<li>
<p><strong>REST API Access</strong> — Built-in REST endpoints for stats, health checks, logs, settings, exports, and per-image actions — all protected with nonce and capability checks.</p>
</li>
</ul>
<h3>📊 Know Exactly What’s Happening</h3>

<h3>💡 Best For</h3>
<ul>
<li>Blogs, marketing sites, portfolios, and eCommerce stores that want fast, local WebP generation.</li>
<li>Site owners who need bulk conversion <strong>without</strong> relying on third-party optimization services.</li>
<li>Privacy-conscious teams who require all media processing to stay on their own infrastructure.</li>
<li>Anyone who wants clear visibility into image status and real storage savings.</li>
</ul>

Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

Thank you for taking over half of the WordPress dashboard with your giant ad. It motivated me to remove your plugin and install EWWW Image Optimizer instead.

Huge black friday Ad. Stop advertising on my dashboard.


Unfortunately, it does not support WordPress Multisite and Arabic Language.
