We use Image Optimizer at Age of Reason Studios to get the most out of our fashion and homeware website. It seems to really do the trick, compressing product images so that the site runs faster.

Effortless way to fix all of our optimisation problems. When I didn't see the PageSpeed results I was looking for, their support team diagnosed the problem and sorted it for us. Now our score is much higher :)

Worked perfectly! This is honestly a life saver - my images were too large and this just saved a good couple of hours resizing and compressing all of my photos. And the best part? It's low price is 100% worth the value!

This app is a must-have. For less than $5, I saved myself a whole day's worth of individually compressing and re-uploading images to my site.

Shopify stores tend to be slow. Compressing your images will definitely help!

Note: Since Shopify uses a CDN, the changes won't be drastic, and won't be evident for a day or two. If you compress your images and then immediately run a new speed test, you will most likely be re-testing a cached (i.e. uncompressed) version of your photo, and therefore won't see much, if any change.

This is such an excellent app! Exactly what I've been looking for, having tried various image compressing apps on Shopify. Image Optimizer is quick, transparent, user friendly with their nicely organized interface, and great customer support (got an answer to my question the next day - impressive given the time difference!). We sell antiques, art and collectibles, which means that we have thousands of high quality images floating on our website at all times and needing constant optimization. I look forward to continue using Image Optimizer, very happy so far.
