<p>No account. No API. No images leaving your server.</p>
<p>Shrinkwell helps you compress images, convert them to modern formats and reduce backup size by finding possibly unused media in your WordPress database. Processing stays local, with no media files uploaded externally for optimization.</p>
<p>Run a 5-image test, review the results, then optimize your full media library with more confidence.</p>
<h4>Built for agencies and freelancers handing off client sites</h4>
<p>Shrinkwell was designed for the moment before you hand a site back to a client and need to prove the optimization work was actually done.</p>
<ul>
<li>Safe test run — optimize 5 images first and inspect the results before touching the full library.</li>
<li>Original backups — keep originals before files are replaced, then restore individual images or the full library when needed.</li>
<li>Delivery proof — scan a live page URL and confirm that WebP files are actually being served, not just generated.</li>
<li>SEO scan — find missing alt text and weak filenames without auto-rewriting anything.</li>
</ul>
<h4>Compression that doesn’t guess</h4>
<p>Choose a named compression profile or dial in your own settings:</p>
<ul>
<li>Balanced — solid savings with sensible quality preservation. Good for most sites.</li>
<li>High — stronger reduction. Best for image-heavy sites where speed matters most.</li>
<li>Near lossless — minimal quality change. Useful for portfolios and product photography.</li>
<li>Custom — a 1–10 strength slider for full control.</li>
</ul>
<p>Shrinkwell can generate WebP automatically and serve it with a safe JPEG/PNG fallback, with no .htaccess edits and no CDN required.</p>

<h4>What Shrinkwell doesn’t do</h4>

Erdo Image Optimizer: Compress & Convert to WebP/AVIF (SEO Audit, Alt Text, Lazy Load)


Expected another "compress and done" plugin and got a complete image SEO toolkit instead. The standout for me is the 6-point audit score on every image. It tells you exactly which ones have weak alt text, bad filenames or the wrong format, and you fix them in bulk instead of one at a time. The WebP/AVIF conversion handles HEIC from iPhone photos too, and it keeps your originals with one-click restore, so there's basically no risk in trying it.



What sold me as a developer was the depth under the hood. Full WP-CLI support (wp erdo convert/audit/restore), real REST endpoints, a background queue so big libraries keep converting after you close the tab, and clean i18n. That's an unusual amount of care for a free plugin, and it's clearly built to WordPress standards, proper nonces, capability checks and escaping throughout.



Runs smoothly, does what it promises, and no upsell nagging. Highly recommended, and I'm looking forward to where this one goes.


More than a compressor a real image SEO suite


Not just another compressor - the 6-point SEO audit on every image and bulk alt text generation alone save hours of work. WebP/AVIF conversion with automatic original backup makes experimenting risk-free, and the WP-CLI commands and REST API endpoints show this was built by a developer for developers. Highly recommended.


Finally an image plugin that takes SEO seriously

Compress & convert images to WebP/AVIF. SEO-audit every image, bulk-fix alt text, filenames & unused media. Lazy loading & BunnyCDN.
