No account. No API. No images leaving your server.
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.
Run a 5-image test, review the results, then optimize your full media library with more confidence.
<h4>Built for agencies and freelancers handing off client sites</h4>
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.
<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>
Choose a named compression profile or dial in your own settings:
<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>
Shrinkwell can generate WebP automatically and serve it with a safe JPEG/PNG fallback, with no .htaccess edits and no CDN required.
<h4>What you get in the free version</h4>
<ul>
<li>Convert images to WebP and AVIF within the monthly free limit</li>
<li>Manually bulk-optimize JPEG and PNG within the monthly free limit</li>
<li>Preserve existing WebP media items instead of recompressing them</li>
<li>Resize oversized images to a maximum width and height</li>
<li>Strip EXIF/metadata where supported</li>
<li>Optimize thumbnails alongside originals</li>
<li>Generate and serve WebP with automatic JPEG/PNG fallback</li>
<li>Restore individual images or run a bulk restore</li>
<li>Run a Media Cleanup database scan and preview possibly unused images</li>
<li>Review an optimization log with bytes saved, skipped images, and skip reasons</li>
<li>Run a frontend delivery test to confirm active WebP delivery</li>
<li>Run a site scan and apply recommended settings in one click</li>
<li>Works with GD and Imagick, with no external service required</li>
</ul>
<h4>Shrinkwell Pro</h4>
Shrinkwell Pro unlocks unlimited optimization and safe Media Cleanup. That includes unlimited WebP and AVIF optimization, auto-optimize on upload, background bulk optimization, safe bulk cleanup actions, Shrinkwell Trash and advanced cleanup tools.
<h4>What Shrinkwell doesn’t do</h4>
Shrinkwell does not send media files to an external API for optimization, require an account, charge per image, or rewrite alt text or filenames automatically.
<h3>Privacy</h3>
Images are optimized on your own server. The free plugin does not transmit media files externally for optimization.
<h3>License & Assets</h3>
Shrinkwell is licensed under GPLv2 or later.
The included Shrinkwell logo and wordmark are original Levmedia brand assets and are distributed with this plugin under GPLv2 or later.

Shrinkwell Image Optimizer

Optimize images with WebP and AVIF, then review possibly unused media safely.

Looking for a WordPress image optimizer without an API key? Squeeze is a local WebP converter that lets you compress images in WordPress, convert uploads to WebP, and bulk compress your media library without ShortPixel-, Imagify-, or Smush-style monthly caps. Processing runs in your admin browser—unlimited squeezes, full privacy, and no uploads to third-party compression servers.
If you need a webp converter wordpress plugin, a shortpixel alternative without recurring API fees, or an image optimizer without api keys, Squeeze keeps optimization on your server and in your browser instead of a SaaS queue.
Unlike cloud-based plugins, Squeeze:
♾️ No compression limits — squeeze your entire Media Library, not just the first 100–500 images per month. 
☁️ No third-party servers — images never leave your site; processing happens locally in the browser (ideal for GDPR-sensitive and membership sites). 
⚡ Direct WebP conversion — convert JPG/PNG to WebP and replace the original file on disk (no duplicate copies cluttering storage). 
🖼️ Optimize on upload — compress in Gutenberg, GenerateBlocks, and the Voxel theme before files hit the server (Elementor on-upload squeeze is available in <a href="https://pluginarium.com/squeeze/#premium" rel="nofollow ugc">Premium</a>).
The result: smaller files, faster page loads, and lower hosting storage—without SaaS fees or API keys.

<h3>How does Squeeze work?</h3>
Open the Media Library, run Bulk Squeeze, or upload a new image — Squeeze runs Google Chrome team–backed codecs (the same family as Squoosh.app) inside your browser via Web Workers. No account, no API key, no off-site upload queue.
