I have tried dozens of image compressor plugins and most of them had fallen to the subscription model. That's strange given that compression is not a resource-intensive task. This plugin brings back the true spirit of WordPress. It's simple, intuitive, and free for everyone.

It's so good, I even made a video for this plugin.
