Barebones but it does the job

I couldn’t believe how hard it was for me to track down a tool that did what this plugin does: delete the oversized originals after WordPress creates the -scaled versions of uploaded images.

Permanently deleting files is a risky task so I think it would be more reassuring to users of this plugin if it gave some details before they click the link to fire off the action, i.e. maybe a “dry run” that lists the files that would be deleted, without actually deleting them first. But if you know what you’re doing, this is a great, easy-to-use tool for freeing up disk space — potentially a lot of disk space.
