Very easy to use - in fact we wish there were a few more options (i.e. select which images you'd like to optimize, quality adjustments, etc.). This may not be related to the app, but we somehow actually increased page load time after optimizing our images. All things considered, still a great app!

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.

Thank you for sharing your feedback. We’re glad to hear that you had a positive experience with the user interface of our app. Our solution is designed to comprehensively optimize images by compressing them, updating alt texts, and renaming filenames. We’ve made updating alt texts and renaming filenames optional to accommodate a range of needs and preferences.

We understand that our app may not have perfectly met your specific requirements. This situation arises not from a shortcoming in our app’s design but from a variance in expected functionalities. Our approach to optimizing all store images is deliberate, aiming to ensure consistent quality and performance across your online presence.

We’d like to highlight that our app includes a testing feature during the initial setup. This allows users to experiment with different compression levels and assess potential savings. This functionality extends to alt texts and filenames as well, enabling a comprehensive evaluation before any commitment is made.

Your interest in apps that offer specific functionalities, such as filename-only optimization, is completely understandable. We regret missing the chance to provide direct assistance. Our customer support team is always on standby to offer personalized guidance and suggest solutions tailored to your unique needs. By engaging with our support team before leaving a review, we can work together to address any concerns and explore suitable alternatives.

We appreciate your review and look forward to the opportunity to support you in the future, whether through our current services or by guiding you to a solution that more closely matches your requirements.

Great! Definitely worth the price compared to the time required to optimize the images one by one.

Every shopify site that contains images should use this app! We reduced our image sizes by 30% which made a noticeable increase in page load time yet didn't affect our perceived image quality. Super easy to use and takes just under 1 minute to start the process. Great app and would highly recommend!
