Force Regenerate Thumbnails allows you to delete all old images sizes and REALLY regenerate the thumbnails for your uploads.
Regenerate all thumbnails from the Tools admin menu. Regenerate batches of images via the Media Library list mode. Select the images to regenerate and then use the Bulk Actions drop-down menu to Force Regenerate Thumbnails. Use attachment actions to regenerate thumbnails for a single image.
Several filters exist for advanced usage. See more via <a href="https://gist.github.com/nosilver4u/eb858df10521aece2044a3a15ccdd17b" rel="nofollow ugc">this gist</a>.

<li>Move thumbnails to plugin Trash instead of deleting permanently</li>
<li>Restore trashed thumbnails later if needed</li>
<li>Process large libraries in batches with visible progress</li>
<li>Detect orphan thumbnails left behind on disk</li>
<li>Detect probably unused media items across post content, featured images, and common builder data</li>
<li>Regenerate missing image sizes in batches</li>
<li>Review per-size analytics including file counts, storage usage, missing sizes, and orphan counts</li>
<li>Review recent activity logs and reporting summaries for cleanup, restore, backup, and regeneration workflows</li>
<li>Disable selected image sizes for future uploads</li>
<li>Create zip backups for all uploads or a specific year/month folder</li>
<li>Schedule recurring cleanup runs with configurable frequency, size scope, and folder scope</li>
