SpurIT SEO Image Optimizer

does the job and is free. fantastic

nice fast easy. I recommend this

A great tool to reduce your images size.
It compressed all the images in one go but sadly all the alt descriptions for images were gone meaning that you have to enter them again...

I love this! Just installed, but grateful for the free option and 3-1 capabilities!! You guys deserve 5 stars!! I will upgrade if all goes well :)

Don't download its a waste of time, not a photo Optimizer but a SEO selling scam
freezes while downloading and wont allow access to photo optimizer till you sit through 10 minutes of what they can do for your SEO
just be honest SpurIT and just sell SEO
these guys should be thrown off shopify App's

I install the app but every time I click on the app it keeps taking me to the app store and doesn't work.
Your app never work and I deleted the app the same day I installed and now I’m being charge for your app even though I never upgraded. Please remove the charge from my account because I’m not paying for something I didn’t
I never upgraded to use

Fast and Thorough. Great app to optimize your photo alt tags

Only allows you to compress your product images, but just doing those increased my Page speed using the Google PageSpeed Tool by 2 points.

Seems like 1/5 images actually get increased in size by 10X or more- which is concerning, but at least you can go individually revert the compression on the problem image.

Overall worth the free download.
