Biggest opportunity: Add “gist”, “disclosure” and “validate” to your wp.org tags. You rank #5, #12 and #14 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 4 listed these are the slots worth spending.

of downloads still active
At least 200K of 5M lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,772 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 1 release in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

GOOD! I just clicked to start the process without checking any options and it seems to delete all old thumbnails to then create the new ones needed by my new theme, is it correct ?

Absolutely great plugin. Fixed my bad looking woocommerce thumbnails that were generated with wrong dimensions in the past. This topic was modified 6 months ago by barnabas1.

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!

After trying other plugins unsuccessfully, this one worked!

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!
Read on wp.org ↗ - ★★★★★ Anonymous1.9y ago
Von aktuell ca. 38.000 Bildern werden immer nur um die 50 bearbeitet und davon kommt abwechselnd bei 10 bis 20 ein Fehler. Da die Fehler immer bei anderen Bildern kommen, ist das auch ein Fehler vom Plugin. Nach den 50 bis 60 Bildern geht es dann gar nicht mehr weiter. Fazit: Leider komplett unbrauchbar das Plugin.
