  • Excellent App

    I had around 900 images on my site. Many were already optimized, but several hundred were PNG files that needed to be reduced. This app took them down in size (webP) over 90%, and did it quickly, without over usage on my server. This was with the free version and I plan to upgrade to the Pro soon to take my image reduction the the next level. This app is the BEST around, nothing else comes close!

  • Well done

    It would be nice to add disabling scheduled launch. Manual only

  • Best Plugin

    The best plugin for image optimization. But after the latest update, there’s a delay when converting Image Features to webp. Although it might just be my feeling. BTW, thanks.
