Great little helper that works away behind the scenes for a resonabe cost. We would be sunk without it. Thank you Loyalty Harbour : )

Very helpful for automatically optimizing our Shopify images and adding alt-texts. Super helpful and responsive customer service.

Fairly priced, super easy to use, intuitive and quick. Highly recommended!

— The Dragon Shop

I've had this connected to my store for a little over 3 years. I never have to worry about compressing image files. Not much else to say. I'm happy with it.

Good app! Would love an option to download all, but does what it says on the tin well.

— Delphian Records

really easy-to-use and helpful app!

— Impact Shop

aplicativo espetacular, além de comprimir as imagens ainda melhora o ranque do Google, recomendo muito!!!

— JJML A LOJA CERTA

I cannot praise this feature enough—it's truly remarkable! One of the aspects I admire the most is that it eliminates the need for manual image compression. It's such a time-saving and convenient feature that I highly recommend to everyone. Trust me, you'll be amazed by how effortlessly it handles image compression for you.

Excellent application, easy to understand and use. I will recommend it must have an app for all shopify stores...

Absolute perfection it worked pretty well but too limited for the free plan i wish i could have free plan and optimize other images but still very good!

— CartEx

Disappointed, removing app after years of use, to try something else with better service.

UX is pretty good, but you can't choose which images to optimise. So the free plan is quickly made useless as it just works on all images in the store - even those which are already optimised from a previous app. Also, you can't just run it in filename mode, it has to optimise (compress) as well, which is not right for our use case.

— Pixie Wing

Poor user experience and very tricky. - When installing the app, you are immediately taken to a workflow that forces you to optimize all of your website photos regardless of whether you want to or not. - It won't let you see the "optimised" version in full size. - The free plan basically consumed in this initial "optimization" - The help centre has not been updated since 2018...

Never again ! You cannot choose which images to edit. The image description doesn't make sense and doesn't match the URL. I can now re-edit over 1000 images.

They are lying, Tried it on my store, it said saved 4.9 MB, went to check stats on GTMETRIX and GOOGLE PAGE SPEED and literally nothing was changed.

Utilizar este app não mudou nem 1% da minha loja. Foram 10$ jogados no lixo. Eu não vi nenhuma melhoria em nenhum lado. É como se nada tivesse sido feito.

— SHOP STOCK PT

I installed an paid for the app because I had 8000+ images that slowed down my site. The app promised from 30% or more reduction but did not - less than 1% on each image is simply not worth paying for. Also I send a message to company before buying but they never answered. The app is too simple, the price is far too high compared to the simplicity of the app and the effect meaning reduction of siz...

The app was not helpful at all. It pretty much messed up my images and I had to remove the app and reload all of my images. Then I was being for a few months after I uninstalled it. I had screenshots from Shopify that clearly stated that I had uninstalled but the developer kept arguing with me. I finally got reimbused but it was an ordeal.
