Fixed my bad looking woocommerce thumbnails that were generated with wrong dimensions in the past. ![](https://secure.gravatar.com/avatar/70028ef7574c859f9e42dcff9f155a183b49b7999f2d9f57287a62893cd30685? s=60&d=retro&r=g) ### 󠀁[This plugin literally saved my website with over 50,000 products.](https://wordpress.org/support/topic/this-plugin-literally-saved-my-website-with-over-50000-products/)󠁿 [koultti](https://profiles.wordpress.org/koultti/) 2025 年 12 月 6 日 1 回复 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! ![](https://secure.gravatar.com/avatar/5c28c3cb9455822dee548170805ccb7e9a6f3c5a01ba501fb7a05f691d6e7fb4? s=60&d=retro&r=g) ### 󠀁[Solve the problem!](https://wordpress.org/support/topic/solve-the-problem-3/)󠁿 [jofer](https://profiles.wordpress.org/jofer/) 2025 年 11 月 7 日 1 回复 It works very well!

It deletes the unregistered ones AND it also seems to repair the meta data. Impressive!
