This module seems to be the best image optimizer out there. It's still in the early stage, and there are multiple great functions missing, but he is very willing to add new functions if you request them with him. Please note, he is a solo developer, so there will be some delay in response, we had around 1 week from our first to final chat. But the final update was worth the wait. I don't use the Alt title optimize function, as i have my own make.com flow to update the images alt title based on a lot of variables. But that might come into the app here some day

It do optimize the images, but it scale them down to 1024x1024 and rename the images to something totally random and useless. The support is not there. Sooo good app, the idea is good, but the resize and change of image names are really bad.

Stop looking and just use this app. It's completely free and perfectly optimizes images without quality loss. My site got much quicker! Thank you to the dev for this beautiful gift of an app!

Cannot in good faith recommend this app. Absolutely ZERO customer service and there is a very obvious glitch in the app and seemingly no way to fix it. My website has few thousand images but after this app compresses the image it makes a duplicate, and then strangely that duplicate is then compressed, then find another duplicate has been made! According to the app I now have close to 15,000 images and the number keeps rising every day even when I do not add any extra products! The app never manages to compress all of my images because it just keeps adding to the number. This also seems to be affecting the loading speed of my site - Before adding this app according to Shopify my loading speed was 'Good' it has now changed to 'Moderate'. There have been no other changes to my site apart from installing this app. Have tried contacting them on numerous occassions but no one bothers to reply. I even contacted the email address that they left in a reply to feedback to another customer hoping it would get a reply but again it has been ignored. I have no choice but to uninstall this app and work hard to fix any damage it has done.

I installed the Pix Image Optimization to the shop, Lorenza theme and it caused all of the images to become blurry when I zoomed in. Hopefully, I will get customer support help to reverse this back.

The app has crunched my images, they seem to load nice and fast now, without any noticeable loss in quality. I had a question for support and they helped me out right away.

Today must have been my lucky day to find this app. It's very easy to use. Customer service was going to compress all my images etc but I had already finished. To know that the customer support was willing to help is amazing. Thank you for allowing this app to currently offer free services. It's not always easy starting a business when you're coming from the bottom. A relief of fresh air. Thanks again!!
