<li>No api key required</li>
<li>Uses your own CPU and disk I/O</li>
</ul>
<p><strong>Cloud/API processing (api key required)</strong><br />
Offloads heavy image work to the Web Wonderland Image API.</p>
<ul>
<li>Uses a remote worker to generate WebP/AVIF for originals and all sizes</li>
<li>Reduces CPU load on your hosting, useful for busy or shared servers</li>
<li>Quotas and limits depend on your Lite, Pro or Unlimited plan</li>
<li>Works alongside local mode   you can always fall back to local processing</li>
</ul>
<p>You can choose your preferred processing mode in <strong>SEO Image Optimiser – Settings</strong>.</p>
<h3>Free (Lite API Key)</h3>
<p>The Lite API Key requires <strong>no card</strong>, only an email to issue an API key.</p>
<p>Included in the Lite API Key plan:</p>
<ul>
<li><strong>Unlimited local image conversions</strong> (WebP/AVIF) on your own server</li>

<h3>What Robin Does</h3>
<p>Robin improves WordPress performance by optimizing images throughout your entire workflow. Images are optimized automatically when they’re uploaded, and existing images in your media library can be optimized in bulk. This reduces manual work and keeps your site fast as it grows.</p>
<p>By compressing images and converting them to modern formats like WebP, Robin helps reduce overall page size. This results in faster load times, better performance metrics, and a smoother user experience, especially on mobile devices and image-heavy pages.</p>
<p>With Robin, you can:</p>
<ul>
<li>
<p>Automatically optimize images on upload</p>
</li>
<li>
<p>Bulk optimize existing images in the media library</p>
</li>
<li>
<p>Convert images to modern formats like WebP and AVIF in <a href="https://robinoptimizer.com/upgrade/?utm_source=wordpressorg&utm_medium=readme&utm_campaign=whatrobindoes" rel="nofollow ugc">PRO</a></p>
</li>
<li>
<p>Reduce image weight and overall page size</p>
</li>
<li>
<p>Improve loading speed and PageSpeed audits</p>
</li>
<li>
<p>Run everything locally without API keys or CDN dependencies</p>
</li>
</ul>
<p>This makes Robin a reliable choice for bloggers, content websites, and performance-focused WordPress sites.</p>
<h3>Why Image Optimization Matters</h3>
<p>⚡ The lighter the image, the faster your page loads.</p>
<p>Images are often the most significant contributor to page size on WordPress websites. As mobile usage continues to grow, image optimization has become essential for delivering fast, responsive experiences.</p>
<p>Unoptimized images can lead to:</p>
<ul>
<li>
<p>Slower page loads</p>
</li>
<li>
<p>Higher bounce rates</p>
</li>
<li>
<p>Poor ad and conversion performance</p>
</li>
<li>
<p>Lower engagement on mobile devices</p>
</li>
</ul>
<p>Image optimization reduces image file size while preserving visual quality, helping pages load faster without sacrificing quality.</p>
<h3>How Robin Optimizes Images</h3>
<p>Robin analyzes each image and applies compression based on the selected optimization mode. Optimization happens automatically and safely, without blocking the WordPress admin interface or requiring manual intervention.</p>
<h4>⚙️ Automatic Image Optimization</h4>
<p>Images are optimized automatically as soon as they are uploaded to WordPress. No manual steps are required, and the optimization process runs quietly in the background.<br />
This ensures that all new images added to your site are optimized by default, without interrupting your workflow.</p>
<h4>📦 Bulk Image Optimization</h4>
<p>Robin supports manual bulk optimization for images that already exist in the media library. With a single action, you can start optimizing previously uploaded images.<br />
The optimization process runs in batches, making it suitable for large media libraries with thousands of images. This is especially useful for existing WordPress sites that want to reduce page size and improve performance without re-uploading content.</p>
<h4>🎚️ Compression Modes</h4>
<p>Robin provides multiple compression modes so you can choose how aggressively images are optimized.</p>
<ul>
<li>
<p><strong>Lossless compression:</strong> Reduces image file size without any visible or measurable quality loss. Ideal for logos, illustrations, and high-fidelity images.</p>
</li>
<li>
<p><strong>Lossy compression:</strong> Applies stronger compression while keeping quality changes minimal and usually unnoticeable. A great default for most WordPress sites.</p>
</li>
<li>
<p><strong>High compression:</strong> Uses more aggressive optimization techniques to achieve maximum file size reduction. Best for performance-focused and image-heavy pages.</p>
</li>
<li>
<p><strong>PageSpeed compression (<a href="https://robinoptimizer.com/upgrade/?utm_source=wordpressorg&utm_medium=readme&utm_campaign=compressionmode" rel="nofollow ugc">Pro</a>):</strong> Applies optimization settings tuned specifically for improving PageSpeed and performance audits.</p>
</li>
<li>
<p><strong>Custom compression:</strong> Allows you to define your own quality level for full control over optimization behavior.</p>
</li>
</ul>
<h4>🖼️ Modern Image Formats: WebP & AVIF</h4>
<p>Robin converts supported image formats such as JPG, PNG, and GIF into WebP, a modern image format that produces smaller files while maintaining visual quality. WebP images are generated automatically when images are uploaded or optimized in bulk.</p>
<p>Optimized WebP images are served automatically to browsers that support them. When a browser does not support WebP, Robin safely falls back to the original image format to ensure full compatibility across devices.</p>
<p>WebP conversion is available in the free version of Robin with no limits on the number of images. Images are converted automatically and served in the best format supported by each browser.</p>
<p>Robin free supports:</p>
<ul>
<li>JPG to WebP conversion</li>
<li>PNG to WebP conversion</li>
<li>GIF to WebP conversion</li>
</ul>
<p>Other common image formats used in WordPress are also supported, with automatic fallback to ensure compatibility across all browsers and devices.</p>
<p>🏆 <a href="https://robinoptimizer.com/upgrade/?utm_source=wordpressorg&utm_medium=readme&utm_campaign=modernformat" rel="nofollow ugc">Robin Pro</a> adds support for AVIF, a next-generation image format that can deliver even smaller file sizes than WebP in many cases. Safe fallbacks are applied automatically.</p>
<h4>💾 Image Backup and Restore</h4>
<p>Before optimizing any image, Robin stores a backup of the original file. You can restore original images at any time or re-optimize them using different compression settings. This makes it safe to experiment with optimization modes without the risk of permanent changes.</p>
<h4>🧾 Strip EXIF data</h4>
<p>Robin allows you to choose whether EXIF metadata should be removed or preserved during image optimization. Removing EXIF metadata helps reduce image file size and improves privacy. Keeping EXIF metadata is useful for photography portfolios or workflows that rely on image data.</p>
<h4>🔄 Background Image Optimization (<a href="https://robinoptimizer.com/upgrade/?utm_source=wordpressorg&utm_medium=readme&utm_campaign=bgimageoptimization" rel="nofollow ugc">PRO</a>)</h4>
<p>Robin supports background image optimization, allowing images to be processed gradually over time without blocking the WordPress admin interface. Background optimization uses scheduled processing to continuously optimize images, preventing timeouts and performance issues when working with large image libraries or frequent uploads.</p>
<h4>📁 Custom Folder Optimization (<a href="https://robinoptimizer.com/upgrade/?utm_source=wordpressorg&utm_medium=readme&utm_campaign=customfolder" rel="nofollow ugc">PRO</a>)</h4>
<p>Robin can optimize images stored outside the WordPress Media Library, including images located in custom folders such as theme directories and plugin assets.</p>
<p>This is useful for:</p>
<ul>
<li>Custom WordPress themes</li>
<li>Plugins with bundled image assets</li>
<li>Performance-focused sites using custom directories</li>
<li>Advanced or custom-built WordPress setups</li>
</ul>
<h4>WP CLI commands (<a href="https://robinoptimizer.com/upgrade/?utm_source=wordpressorg&utm_medium=readme&utm_campaign=wpcli" rel="nofollow ugc">PRO</a>)</h4>
<h4>Commands</h4>
<ul>
<li>wp robin optimize </li>
<li>wp robin stop </li>
<li>wp robin status </li>
</ul>
<h4>Available scopes</h4>
<ul>
<li>media-library</li>
<li>custom-folders</li>
<li>nextgen</li>
</ul>
<h3>Use Cases</h3>
<p>Robin Image Optimizer fits naturally into a wide range of WordPress workflows, from small blogs to performance-focused websites.</p>
<h4>📝 Blogs & Content Websites</h4>
<p>Perfect for bloggers and content creators who upload images regularly and want automatic image optimization without manual work. Images are optimized on upload, keeping pages fast as content grows.</p>
<h4>🖼️ Image-Heavy Pages & Media-Rich Sites</h4>
<p>Ideal for galleries, portfolios, landing pages, and visual storytelling sites where images contribute heavily to page weight. Bulk optimization and higher compression modes help significantly reduce page size.</p>
<h4>⚡ Performance-Focused WordPress Sites</h4>
<p>Great for site owners focused on speed, Core Web Vitals, and PageSpeed audits. Optimized images and modern formats like WebP help improve loading performance across desktop and mobile.</p>
<h4>🏗️ Existing WordPress Websites</h4>
<p>Useful for established sites with large media libraries. Previously uploaded images can be optimized in bulk without re-uploading or rebuilding content.</p>
<h4>🌍 Sites Without a CDN</h4>
<p>A reliable solution for websites that don’t use a CDN. All image optimization and WebP conversion happen locally inside WordPress, with no external services or API keys required.</p>
<h4>🧩 Custom Themes & Advanced Setups</h4>
<p>Suitable for custom WordPress themes and advanced setups where images live outside the Media Library. Custom folder optimization allows full-site image optimization beyond standard uploads.</p>
