Enfants Terribles digital GmbH

<p><strong>Enfants Img Performer</strong> converts your WordPress images to WebP automatically on upload – without sending a single byte to an external service. Everything runs on your own server, without limits.</p>
<p>The separately available <strong>Enfants Img Performer PRO</strong> plugin unlocks AVIF conversion, bulk optimization and AI-powered alt text generation.</p>
<h4>Why Img Performer?</h4>
<p>Most image optimization plugins send your images to a third-party cloud service for processing – often with monthly quotas and accounts required. Img Performer is different: it uses PHP’s built-in GD library (with Imagick as fallback) to convert images locally. Your images never leave your server. No account needed. No monthly limit.</p>
<h4>What it does</h4>
<ul>
<li>Converts JPEG and PNG uploads to WebP automatically – unlimited, free</li>
<li>Converts all registered image sizes (thumbnail, medium, large, custom)</li>
<li>Rewrites <code>src</code>, <code>srcset</code>, <code>href</code> (lightbox) and lazy-load attributes in the frontend</li>
<li>Deletes WebP files when the original image is deleted</li>
<li>Logs all conversions for transparency</li>
<li>Configurable quality setting (1–100, default 85)</li>
<li>CO₂ savings tracker with optional anonymous global statistics</li>
</ul>
<p>The separately available <strong>Enfants Img Performer PRO</strong> plugin (installed alongside this plugin) adds:</p>
<ul>
<li>AVIF conversion – up to 50% smaller than WebP</li>
<li>Bulk Converter – convert your entire media library in one click</li>
<li>AI Alt Text Generator – WCAG-compliant alt texts via Mistral, Claude or OpenAI</li>
</ul>
<h4>GDPR / DSGVO</h4>
<p>Enfants Img Performer processes all images exclusively on your own server. No image data, IP addresses or personal information is transferred to external services. No API keys required.</p>
<p>The only optional external connection is the anonymous CO₂ statistics feature (opt-in, disabled by default). When enabled, it sends only total bytes saved to our EU-based server – no IP address, no domain, no personal data.</p>
<h4>Requirements</h4>
<ul>
<li>WordPress 6.0 or higher</li>
<li>PHP 7.4 or higher</li>
<li>GD extension with WebP support (<code>imagewebp</code>)</li>
</ul>
<h3>External Services</h3>
<p>This plugin can optionally send anonymous usage data to an external service operated by Enfants Terribles digital GmbH.</p>
<p><strong>CO₂ Statistics (opt-in, disabled by default)</strong></p>
<p>When you enable “Global sustainability stats” in the plugin settings, the plugin sends the following data once per day to our EU-based server:</p>
<ul>
<li>An anonymous random site ID (UUID v4, generated locally, no personal data)</li>
<li>Total bytes saved through WebP conversion</li>
</ul>
<p>No images, no IP addresses, no domain names and no personal data are transmitted. The anonymous site ID cannot be traced back to you or your website.</p>
<p>This data is used solely to display a global CO₂ savings counter on the plugin website.</p>

MegaOptim

<p>MegaOptim 2.0 is a WordPress image optimizer built around three goals:</p>
<ol>
<li><strong>Further compress existing WebP and AVIF images.</strong> Next-gen formats are already small — MegaOptim 2.0 squeezes more out of them while keeping originals intact.</li>
<li><strong>Convert old JPG, PNG, and GIF images to WebP or AVIF.</strong> Modernize your Media Library and serve next-gen formats to supported browsers, with the original file preserved as a fallback.</li>
<li><strong>Optimize old formats in place.</strong> Make JPEG and PNG smaller without changing the format — useful when you want savings but don’t want a next-gen conversion. GIF, WebP, and AVIF compression are available through MegaOptim Cloud.</li>
</ol>
<p>The plugin is <strong>free</strong> when you use the local method (GD or Imagick on your server). For smarter compression — including further optimization of existing WebP and AVIF files — add an API key and use <strong>MegaOptim Cloud</strong>, available for around <strong>$54 per year</strong> on <strong>unlimited sites</strong>.</p>
<h4>Why Use MegaOptim?</h4>
<ul>
<li>Further compress existing WebP and AVIF images for extra savings</li>
<li>Convert JPEG, PNG, and GIF images to WebP or AVIF</li>
<li>Optimize JPEG and PNG in place with no format change (GIF/WebP/AVIF compression via Cloud)</li>
<li>Bulk process the WordPress Media Library</li>
<li>Browse and process folders outside the Media Library</li>
<li>Free local processing or smarter MegaOptim Cloud compression</li>
<li>Automatically convert or compress newly uploaded images</li>
<li>Serve WebP and AVIF with Apache <code>.htaccess</code> or PHP passthru</li>
<li>Track background jobs with a built-in queue monitor</li>
<li>Restore compressed originals from backup or remove generated next-gen files</li>
<li>Optionally process retina images generated by WP Retina 2x / Perfect Images</li>
<li>Use WP-CLI for bulk conversion, stats, reset, logs, and queue tools</li>
</ul>
<h4>Free Local Processing or MegaOptim Cloud</h4>
<p>MegaOptim works without an API key. If your server has GD or Imagick, you can convert JPEG/PNG/GIF to WebP, generate AVIF where your server supports it, and compress JPEG and PNG entirely on your own server — free, forever. GIF, WebP, and AVIF compression are available via MegaOptim Cloud.</p>
<p>For noticeably better results — including further compression of existing WebP and AVIF images, smarter JPEG/PNG optimization, and broader AVIF support — add a MegaOptim API key. MegaOptim Cloud offloads processing from your server and costs just <strong>$54 per year</strong> for <strong>unlimited sites</strong>. Get an API key from <a href="https://app.megaoptim.com/" rel="noopener noreferrer nofollow ugc">the MegaOptim dashboard</a> and see plans at <a href="https://megaoptim.com/pricing/" rel="noopener noreferrer nofollow ugc">MegaOptim pricing</a>.</p>
