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 this gist.

I rarely use plugins that haven't updated for years. But this plugin not only still works perfectly fine, it's even better than many newer products. I've just tried the plugin by Shortpixel, and it simply did not do the job. It is very likely a setting that was wrong. But common, I just wanted to regenerate all thumbnails after changing the thumbnail size. I don't want to read the documentation for that. "Force Regenerate Thumbnails" is still the winner for me. It's a pitty that it hasn't been updated for so long.

At first I was a bit cautious because the plugin has not been updated in years. So I tested in a staging site first and it worked like a charm. Used it on the production too without any error. It's a great plugin. Does what it is supposed to do.
