Don't waste your time installing this plugin. There are some free images and after that you have to pay. There are other free plugins that do the same.

I never leave negative reviews, but this is literally the worst experience. I purchased the expensive plan and should have had 1000 image credits. However, credits are deducted for processing broken images, unpublished images, and whenever plugin throws an error - the credits are still deducted. Lost 500 credits just "trying" to process it. Emailed support 3 times during the past 10 days - NO reply whatsoever. Asked for a refund - no answer. Can't believe this is a part of the WordPress plugin directory... Btw, payments are only accepted via credit card, and you cannot easily delete it or cancel your account - have to email support, which doesn't react...

Quickly uninstalled after having to sign up. You get only 10 images for free, seriously?! After that you need to pay €XX/month. I feel like you're not being honest in your plugin description. This is not a free plugin. Other plugins do this for free.

For even a personal blog this isn't worth it. I installed then quickly uninstalled this plugin when it nagged me to buy credits to finish the job. I'm not a fan of plugins that are advertised as free then force you to pay to use. If I wanted a premium plugin I would have just searched for that and paid. Honestly there are a bunch of similar plugins that all do the same thing for free. Optimizing 10 images would have been faster to do in person than through the optimizer - I just don't see the value.
