I love the app. Thanks. Installation was easy. It helped save space and renaming the variants was good.

I used this app to compress the pictures that were already in my Shopify store. 103 pictures. This included icons and product pictures - actually, it turned out that it compressed every single picture that was on file. Then it renamed them and put in Alt descriptions. And, it did it under 1/2 hour. I paid for the subscription after I found out that it will automatically compress every picture I upload to my store, even pictures uploaded via other software. I was also very surprised to find this software actually worked just as it said it would. No problems with anything. It just worked.

Just downloaded seems to be working fine so far https://nguweedshirts.com/collections/420-cell-phone-cases

Wonderful app to make your website load faster. Easy to use and compress images. I would definitely recommend.

I use it to help with Page speed, seems to be a good option if you don't want to do it all manually

Great app! Images have been compressed without losing clarity and we can immediately see that our webpages are loading faster! We also like the SEO Rename feature! Many thanks from all of us at Happy Eco Baby! GOD bless!

we like our images small, very small. very helpful for the management of our large photo library. Thanks!
