Crush: Speed & Image Optimizer

This app adds 13 random characters to the picture name. This forces the user to manually look up the picture name every time. In addition, this number detracts from the picture's SEO. If it wasn't for this added number the app would be more useful to us and my review would be more positive.

Pro: it only allows you to optimize to a certain point so that your pictures should still look great.
Con: The interface+process needs work and you're charged via file size. And if you try out all 3 modes of optimizing then you're charged 3x for the same 1MB picture.

Doesn't work with our image.

We wanted to make sure the compression algorithm for lossless was powerful enough (30% announced sounds quite low in comparison to tools like TinyPng), so we ran a trial on one specific product.
We optimized all images, lossless at first, then a few with lossy compression.

The app says xx% compression, but Google Page Speed says nothing changed.
Ok, we downloaded ...

I installed the app on my shopify store, but after I tried to open it the only thing I see is a blank white page. I don't think it works

Not impressed. It counts the size of your entire image towards the quota, not just how much it saved. If my images were already all optimized, I'd run out of bandwidth, even though I shouldn't, because there's nothing to optimize.
