<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>Privacy</h3>

<p><strong>Erdo Image Optimizer</strong> is not just another image compression plugin. It is a complete <strong>Image SEO & Performance Suite</strong> that covers WebP/AVIF conversion, bulk alt text management, filename sanitization, lazy loading, unused media cleanup, and a 6-point SEO audit — all in a single, modern dashboard.</p>
<p>Most image optimization plugins stop at compression. Erdo goes further: every image in your media library receives a <strong>professional SEO health score (0 out of 6)</strong>. You will know exactly which images are hurting your Google rankings and how to fix them, in bulk, in minutes.</p>
<h4>Why Erdo Image Optimizer?</h4>
<ul>
<li><strong>Image SEO Audit (6 Points):</strong> Every image gets a score from 0 to 6 based on alt text, filename quality, title, contextual relevance, dimensions, and format. Fix failing criteria with one click — no guesswork.</li>
<li><strong>WebP & AVIF Converter:</strong> One-click conversion from JPEG, PNG, GIF, and HEIC/HEIF to WebP or AVIF. Smart Quality mode automatically finds the smallest file size that still looks great.</li>
<li><strong>Bulk Alt Text Generation:</strong> Automatically generate descriptive alt text from filenames for every image missing it. Fix hundreds of images in seconds — critical for accessibility and image SEO.</li>
<li><strong>Filename Sanitizer:</strong> Transforms messy uploads like <code>IMG_1234 (copy).JPG</code> into SEO-friendly <code>professional-web-design.webp</code> at upload time. Bulk-rename existing images with automatic database reference updates.</li>
