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.

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...

Thank you for sharing your feedback with us. We understand your concerns and would like to offer some clarification to ensure the best experience with our Image Optimizer app.

When selecting a plan, our app immediately begins optimizing images according to the limits of the chosen plan. Our free plan, designed for testing purposes, optimizes up to 50 images. This feature was implemented with the intention of providing a straightforward way for users to assess our app’s capabilities before committing to a paid subscription. For those who prefer not to use the test option, we provide extensive examples across various features to aid in making an informed decision without further testing.

We take pride in the robustness and stability of our app, which has been serving the Shopify community for over 7 years. Our detailed reporting on optimized images includes comparisons of original and compressed sizes, savings percentages, and alt text modifications, all aimed at providing a comprehensive overview of the optimization process. If finding this information or viewing the optimized images presents any challenges, we strongly encourage reaching out to our support team for assistance. We are dedicated to offering help and guidance, recognizing the impact of positive feedback and the weight negative reviews can carry.

Regarding your paid plan selection, it appears there may have been some misunderstanding about our free plan’s purpose and the extensive features available through paid subscriptions. We regret any confusion and are more than willing to discuss adding the one-time 50 free images to your account, should you find it necessary, despite this request being unprecedented.

Our Help Center is a repository of information, created and refined since 2016, to address the common and uncommon queries of our users. It’s designed to be comprehensive, but we are always open to updating and adding new articles in response to emerging customer needs or inquiries.

We sincerely apologize if your experience did not meet expectations. Our team values the opportunity to assist and improve your experience. Before leaving a review, whether positive or negative, we kindly ask that our users contact us with any issues. Our reputation in the Shopify community for exceptional support is something we hold dear, and we are here to help resolve any concerns.

Thank you for your feedback, and we look forward to the opportunity to make your experience with our app a positive one.

Hi Emma,

Thank you for taking the time to leave us a review, and we are thrilled to hear that you find our app great! We appreciate your feedback and understand that you would like to see some improvements in our app.

At present, our app can automatically optimize product, collection, asset, and blog post featured images, but we are unable to optimize some other images due to limitations imposed by Shopify. However, we have a highly experienced team that is always ready to help you with any issues or questions you may have, even if they are outside the scope of our app. So, please do not hesitate to reach out to us for support.

We are located in Sydney, Australia, and it is always a pleasure to see great stores from our home country. We wish you every success in your business, and we are committed to providing you with the best possible support.

Once again, thank you for your support and your feedback. If you have any further questions or concerns, please feel free to contact us anytime!

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.

Hi Marco!

This is Alex from the Image Optimizer Support Team, and I want to sincerely apologize for your negative experience with our app.

Our app is specifically designed to help optimize hundreds or even thousands of images in a Shopify store automatically. To aid in the setup process, we provide examples from your store below the compression types, alt text templates, and filename templates. These examples usually help our clients understand how our app works and what they can expect when choosing one of our plans.

Upon checking your account, I see that our app is still installed, which is great news. You have the option to restore all your original images if you are not satisfied with the results. You can do that in our app by going to App - Settings - Restore all images.

Additionally, I reviewed your original alt texts and filenames and found that almost all of the images did not have alt texts, and the previous filenames were not SEO-friendly. Our app updated your alt texts and image filenames using the template that you confirmed during the setup.

For example,

Original alt text:
Optimized alt text: Canon 521 Multipack Tintenpatronen original Canon Druckerpatrone Pixma Drucker

Original filename: 57_fec89142-e24e-47e2-8b46-0753d44eebcd.png
Optimized filename: canon-521-multipack-tintenpatronen-original-canon-druckerpatrone-pixma-drucker-837904.jpg

Regarding the image description not matching the URL, I wasn't able to locate any issues with the images upon review. Our app uses the template that you confirmed during the setup process, and I'd be more than happy to investigate further if you could provide additional details about the problem.

Once again, we apologize for any inconvenience caused and are committed to making things right. Please check the optimized images again and let me know. I still hope that there is some kind of misunderstanding, and we will be happy to help you resolve any issues you may be experiencing.

In addition, we've also sent you an email regarding your review and are eagerly awaiting your response. We want to make sure that we fully understand your concerns and address any issues as soon as possible. Thank you for your patience and understanding.

Regards,
Alex T.

Thank you for your feedback. We checked our logs and can confirm that our app successfully compressed 50 images and saved 44%.

We also noticed that you only compressed some of your images because the FREE plan includes only 50 images. In addition, you didn't compress your homepage banners using our Manual File Uploader.

Google PageSpeed Insights and other testing tools warn about website speed issues. We analyzed your store and noticed that your homepage had a review widget that slows down your store. The review widget uses images from AliExpress servers and doesn't use such essential features as responsive images and lazy loading. Official Shopify themes have been using these crucial features for many years. If you want to improve the speed of your website, you should contact the developer of the review widget and ask them to check your store.

I am also sorry that you didn't give us a chance to check your account and your store :( We also tried to contact you today. Unfortunetely, we received the following email: "Message not delivered. Your message couldn't be delivered because the remote server is misconfigured.".

Please get in touch with us anytime, and we will be happy to help you!

Hi there!

Alex here from the Image Optimizer Support Team!

Thank you for your feedback. I’m sorry you had that experience. Please find my comments below.

1. Image Compression

I checked our logs and noticed that our app had reduced the size of your original images by 64% (Original: 318.9 MB, Optimized: 116.1 MB, Saved: 202.8 MB ). Please note that this is the average savings for your account, and many images were compressed by more than 80%!

Our app uses best-in-class compression algorithms. Unfortunately, your images can be compressed more only with significant quality loss. If we compress your images further, they will look blurry and unprofessional.

I also noticed that you wrote that it stayed the same even 1% of my store. Please provide more details about what you mean because our app has saved 64%, and it is unclear what 1% means. We are well-known in the Shopify community for being helpful even if a problem lies somewhere else!

2. Homepage banners

I also checked your store and noticed that you didn't compress your homepage banners using our Manual File Uploader. So I will compress them manually for your convenience and send them to you in a separate email.

3. Refund

If our app doesn't meet your needs, we want to make things right! So please check your email and let us know.

I'm looking forward to hearing from you!

Regards,
Alex

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.

Image Optimizer helped me to solve a massive problem. Firstly the supplier photos that I received were HD and way too big, and using other tools on google didn´t compress the quality well enough. Their manual uploader function saved me alot of time messing around with other tools. Also Support reset my billing cycle for free because I had a load of images that I wanted to seperate from the main images but couldnt. so they let me optimize everything and gave me a free quota for the month. They even reply on weekends!
