Absolutely great plugin. Fixed my bad looking woocommerce thumbnails that were generated with wrong dimensions in the past.

I was completely stuck—my site was overloaded with heavy PNG images and more than 100,000 unnecessary thumbnails. I was seriously considering deleting everything and rebuilding the whole site from scratch. Every thumbnail regeneration plugin I tried would either freeze, fail to delete the old thumbnails, or just generate even more useless image sizes. Then I found this plugin, and honestly, it was a game changer. I used it together with two other tools:• Image Sizes Controller by GrandPlugins — I disabled every thumbnail size I didn’t need and kept only the one that mattered. Before that, WordPress was generating around 10 different sizes for each image.• Plus WebP or AVIF by Katsushi Kawamori — This one converts any uploaded image to WebP with adjustable quality and deletes the original file. Simply perfect. Now my website is faster than a bullet. After installing and configuring the other two plugins, I tested everything and then started the full thumbnail regeneration process using Force Regenerate Thumbnails. To my surprise, it worked flawlessly: no freezing, no errors, and the whole process was impressively fast. All the old oversized images were completely removed, and every thumbnail was regenerated exactly as needed. A HUGE THANK YOU to the developer of this plugin. You genuinely saved my project. Wishing you all the good things in the world!

The plugin regenerates the image sizes that are registered. It deletes the unregistered ones AND it also seems to repair the meta data. Impressive! Thank you very much!

Unlike other plugins that claim doing the same, this one works and still every image keeps being displayed correctly on the site. Thanks for this great tool!
