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!!

I have around 2,500 images on my site. Navigation is running much quicker than before and I've saved over 40mb with optimisation. Recommend for anyone with a large volume of images. Thanks guys!!

I like that the App helped me optimized my site, reducing the size of my images, causing my site to move faster. I will recommend this app if you have a slow shopify store.

Looks great! I had a lot of images (over 2500) so it took a long time to optimize all of them but they look great and the site loads SO much faster on mobile. Thank you!
