Superior Vacuums

I use this app to do watermarks, I works great!!!


I used the app for a little. It does a great job in Seo and overall optimization. But 1 of the promised function is not working that is why i deleted the app. The app supposed to shrink or grow the images to the same size while compressing them. It does shrink and compress but it does not grow the images to the set size. The support is good even though they still think the app does grow the images. They refunded the money and cancelled the subs. I made a video about the problem but couldnt send them because of the video size. I try compressing it but that way you cant understand what is going on, quality gets so bad. The other functions work fine so if you want to only shrink or you want to fill the images the app is good.


Very useful. Cant say enough. Ive only been using the Free Feature but its good enough for what i want.

Yes, this app will help you speed up your site using compression, especially if your original photos are big and heavy!

don't think anything is free. Or maybe i am not sure. but it asks for money if you want to run the app. even it meets the min criteria.

Hi, yeah there's lots of free features. In fact, every section has unlimited free usage, particularly for testing. However, if you want to bulk process your products or your shop, there will be a small fee depending on your shop size. Please enjoy!

Thanks for the review! I hope you continue to enjoy the app!


Top, really useful, unfortunately the free version is long to do we have to do it manually.
The paid version is better.


Nice app to edit pictures for displaying on a website, nice experience to work on this app, i must refer others to use this app


Pretty good, lots of useful features. I'm just now launching my store so I'm not sure how effective it will be yet, but seems like it will be helpful
