Worked really well - looks like everything got optimized and it was super easy to use - it really is a point and click app. Best part, totally integrated with Shopify so I didn't have to create an account or go through any billing pages - just billed my account directly. Highly recommend.

The best $36 I ever spent. My website was full of un-optimized images that were dragging the load time down and hurting my google rating, not to mention the bounce rates I had from impatient customers! Optimizer fixed my entire website in just a couple hours and my site now loads instantly. Thanks!!

Every shopify site that contains images should use this app! We reduced our image sizes by 30% which made a noticeable increase in page load time yet didn't affect our perceived image quality. Super easy to use and takes just under 1 minute to start the process. Great app and would highly recommend!

Hi,

We have just successfully optimized 2818 images with "Image File Size Optimizer" and we saved 66.7 MB of space and must say that it works really well. It was very easy to setup and use - like 2 clicks and it was done.

So 5 stars from us ;-)

Thanks

Great support for this app: I was having trouble with my site speed and reached out to Alex for helps I thought the images might be to blame. He was very helpful in explaining certain things! The site is loading quicker thanks to a few quick actions Alex suggested. Its a great resizing app that works really well.

Thank God for this application. In just one click, almost 400 images in my site were optimised by this application. If I were to do this alone, it will take me ages and my time is very valuable. I couldn't thank the author enough for making this app available. I will recommend it to all my friends who have Shopify site.

This is a great app. I installed and it does everything in the background. Anytime I upload a new product picture it automatically optimizes the image. I wish it could work on all photos in shopify, I have a lot of blog photos that I have to manually optimize. Apparently no optimizing photo apps can't access those pictures for blog posts.

I had some images that weren't being optimized. I asked for help and while these images turned out to not be product images (they were banners and other images in the site), they gave me direction on how to fix it, and even sent me some resized images. They didn't have to go that extra mile, but they did! Very helpful and fast communication!

Love how easy and straightforward it is to use! Instead of going through the time consuming hassle of compressing each and every photo myself, all it took was one simple click of a button, really amazing!! I also don't have to worry about losing my original photos as they are stored for 30 days with them and can be easily restored. Will definitely continue to use them :)

Very very good customer service. I had questions before installing this App and Vitalii, the customer service rep, answered all my questions thoroughly plus gave me some more insight into how I can get our website load time to speed up. After I installed it, the directions and process of optimizing my photos was simple and the instructions were easy to follow. Highly recommend this app!
