Shrinkwell Image Optimizer vs Converter for Media – Optimize images | Convert WebP & AVIF

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. Built for agencies and freelancers handing off client sites 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. Safe test run — optimize 5 images first and inspect the results before touching the full library. Original backups — keep originals before files are replaced, then restore individual images or the full library when needed. Delivery proof — scan a live page URL and confirm that WebP files are actually being served, not just generated. SEO scan — find missing alt text and weak filenames without auto-rewriting anything. Compression that doesn’t guess Choose a named compression profile or dial in your own settings: Balanced — solid savings with sensible quality preservation. Good for most sites. High — stronger reduction. Best for image-heavy sites where speed matters most. Near lossless — minimal quality change. Useful for portfolios and product photography. Custom — a 1–10 strength slider for full control. Shrinkwell can generate WebP automatically and serve it with a safe JPEG/PNG fallback, with no .htaccess edits and no CDN required.

AVIF support Now in the PRO version you can use AVIF as the output format for your images. The AVIF format is a new extension — is the successor to WebP. Images converted to the AVIF format weigh about 50% less than images converted only to the WebP format, while maintaining better image quality. Enjoy peace of mind knowing that AVIF is supported by over 90% of browsers. And if any visitor has an older browser, our plugin will automatically fall back to WebP — so every user gets fast, high-quality images without a hitch. Unlock the magic of AVIF in our PRO version — upgrade today for unparalleled image performance. How does this work? When a browser tries to load an image file, the plugin checks if it supports the AVIF format (if enabled in the plugin settings). If so, the browser will receive the equivalent of the original image in the AVIF format. If it does not support AVIF, but supports the WebP format, the browser will receive the equivalent of the original image in WebP format. In case the browser does not support either WebP or AVIF, the original image is loaded. This means full support for all browsers. A guide on how to test whether the plugin is working properly can be found here. Additional information If you have just installed the plugin, you can optimize images with one click.
