<p>Shrinkwell Image Optimizer helps WordPress site builders optimize images locally, without an external API or account. It compresses JPEG/PNG images, creates WebP and AVIF versions where supported, keeps original backups, checks image SEO, and gives clear proof of delivery and savings.</p>
<p>Use the safe 5-image test first, review the result, then optimize the full media library with more confidence.</p>
<h4>Local-first optimization</h4>
<ul>
<li>Automatically optimize JPEG and PNG uploads on upload.</li>
<li>Preserve existing WebP media items instead of recompressing them.</li>
<li>Choose from Balanced, High compression, Near lossless, or Custom compression profiles.</li>
<li>Use controlled compression settings designed to preserve quality while reducing file size.</li>
<li>Resize oversized images to a maximum width and height.</li>
<li>Optimize thumbnails and strip image metadata/EXIF where possible.</li>
</ul>
<h4>Safe media library workflow</h4>
<ul>
<li>Run a safe 5-image optimization test before committing to a full media library run.</li>
<li>Optimize existing images directly from Media > Shrinkwell.</li>
<li>Review saved space, skipped files, and recent results before continuing.</li>
</ul>
<h4>WebP and AVIF delivery checks</h4>
<ul>
<li>Generate WebP versions when supported by your server.</li>
<li>Generate AVIF versions when the local AVIF encoder and safety checks pass.</li>
<li>Use the local <code>cwebp</code> binary when available, with WordPress image editor fallback.</li>
<li>Generate missing WebP files without recompressing originals.</li>
<li>Serve AVIF first, then WebP, with safe JPEG/PNG fallback markup.</li>
</ul>
<h4>Page Proof reports</h4>
<ul>
<li>Run a Page Proof scan on a live frontend page to verify modern image delivery, estimate image payload savings, and identify cached JPG/PNG URLs.</li>
<li>Copy or download a plain-text proof report for your own checks or client handoff.</li>
</ul>
<h4>Image SEO Check</h4>
<ul>
<li>Find images with missing alt text, weak alt text, and weak filenames.</li>
<li>Use safe one-click alt text suggestions when Shrinkwell has a reliable source.</li>
<li>Avoid blindly reusing random filenames, GUIDs, or camera-style names as SEO text.</li>
<li>Save alt text inline without leaving the Shrinkwell screen.</li>
</ul>
<h4>Backups & Restore</h4>
<ul>
<li>Keep original backups before replacing any files.</li>
<li>Restore all optimized images at once from a single screen.</li>
</ul>
<h4>Quick Start</h4>
<ol>
<li>Install Shrinkwell and open Media > Shrinkwell.</li>
<li>Run the 5-image safe test.</li>
<li>Review savings, skipped files, and backups.</li>
<li>Run Media Optimization for the full media library.</li>
<li>Use Page Proof to verify WebP/AVIF delivery on a real frontend page.</li>
</ol>
<h4>Insights & Logging</h4>
<ul>
<li>View optimization status directly in the Media Library list view.</li>
<li>Review an optimization log showing saved bytes, WebP/AVIF counts, and skipped files with clear reasons such as file size, dimensions, and processing limits.</li>
<li>Review current settings from the Overview page at a glance.</li>
</ul>
<h4>Settings & Recommendations</h4>
<ul>
<li>Configure everything from the Shrinkwell admin page under Media > Shrinkwell.</li>
<li>Scan your media library and receive tailored setting recommendations for your site.</li>
<li>Apply recommended settings in one click after scanning.</li>
<li>Scan for image SEO issues without automatically modifying content.</li>
</ul>
<p>Review prompts appear only after Shrinkwell has produced measurable results.</p>
<h4>What Shrinkwell Does Not Do</h4>
<ul>
<li>Does not send images to an external optimization service for core local features.</li>
<li>Does not require an account for free local optimization.</li>
<li>Does not automatically rewrite SEO content.</li>
</ul>

<h3>Why WebP?</h3>
<p>WebP is a modern image format developed by Google that provides both lossy and lossless compression for images on the web. Here are some benefits of using WebP:</p>
<ul>
<li><strong>Smaller File Size</strong>: WebP images can be up to 30% smaller than JPEGs and PNGs with no noticeable loss in quality, resulting in faster page load times.</li>
<li><strong>Transparency and Animation</strong>: WebP supports transparent backgrounds like PNG and animated images like GIF, making it a versatile choice.</li>
<li><strong>Improved Compression</strong>: WebP offers better compression algorithms compared to traditional formats, allowing for high-quality images with lower storage requirements.</li>
</ul>
<h3>Why AVIF?</h3>
<p>AVIF (AV1 Image File Format) is a cutting-edge image format derived from the AV1 video codec, offering even better compression than WebP. Here’s why AVIF is beneficial:</p>
<ul>
<li><strong>High Compression Efficiency</strong>: AVIF can reduce image sizes by up to 50% compared to JPEG, while maintaining similar or even higher visual quality.</li>
<li><strong>HDR Support</strong>: AVIF supports High Dynamic Range (HDR), allowing for more vibrant and detailed images, especially on modern displays.</li>
<li><strong>Advanced Features</strong>: It includes support for transparency, animation, and a wider color gamut, making it suitable for various types of web content.</li>
