Wonderful app and phenomenal personalized support from Vitalli! Truly above and beyond customer service experience.Very fast optimization results...Our Google Page Speed Insight scores went from 55 mobile/58 desktop to 65 mobile/86 desktop in a matter of hours. I'm so thankful that we discovered this app and highly recommend this service to help improve website speed. Deborah @ clothedwithtruth.com

Easy app to use, does what it says by optimizing your pics within a set range and so far I'm happy with the results. I've used other optimizers so lots of my pics were already optimized and this app found an additional 1% BUT when I used it against good quality pics that weren't optimized, it save up to 90% in space, keeping good quality. If you don't like the results, just roll back. Thumbs up!

Can't recommend this app enough. I had mistakenly uploaded all my site images in a large file size and in the wrong format. My images were reduced to a manageable size in a number of hours (there were nearly 15,000 of them), which massively sped up my site's loading time. Further, they offered to change the format of all my images free of charge. They have gone above and beyond to help me - so friendly, so efficient.

Vitalii was super helpful answering all my questions. We ran image optimizer using lossless compression on more than 50k images. Image optimizer handled this large number without any issue. Without any degradation of image quality we saved around 10%. I know we could have saved even more had we gone with the lossy compression option. I would highly recommend image optimizer. Even if you have a large store it works very well.

Needed to improve the speed for my website and tried this app. You can preview some of the images and mine looked the same in the optimized version as the current one so I knew quality wouldn't be an issue. I paid a total of 2,46 USD as a flat fee for the optimization of 246 images. The app converted all the images in around 30mins and I saved 26 % of the total file size. Great app and very user friendly for an affordable price. Highly recommend it!

Been using this product for a while and it worked great. When prepping large product launches I could kick it off and get my images sized right from day 1. When they added the feature that let you prepay with a balance and then automatically scan and adjust, I found that useful to catch images you may forget about - but hurt my ability to line up and process many images at once for a launch. I reached out to them and they helpfully added that feature! The best products are always those made from the feedback of the customers. :-)

When I initially began uploading product photos to our site, I didn't even think about image optimization and suddenly had thousands of images that were obliterating some of my customers' computers, even my own at times. This app works wonders correcting my mistake. It works exactly as intended, and quickly. It's incredibly affordable and saves me the hassle of having to even think about image resolution; instead I can focus on getting photos up quickly while the app does the rest. I absolutely recommend it to anyone with lots of products photos.

Well... there are a lot of SEO picture optimzer out there. I just thought I give this one a try. It really did work well with all the pics on our store at https://www.rheinufer.net and for a great price. The main reson for my 5 Star rating is the support, with IMHO is the huge differentiator. I had a small issue with the app, user proplem, and Igor answered within 5 Minutes. He then offered to sort out the problem himself and within an hour everything was done.
My Google Site speed moved from around 30ish to 70ish with this app and the excelent support!

UPDATE: Had a fantastic customer service experience that went above and beyond in improving our site speed. We were bogged down by some poor optimizations and support helped me fix my errors and achieve excellent improvements just in time for the holiday rush! Highly recommend.

ORIGINAL REVIEW:
My site speed was faster than 69% of websites on Pingdom prior to use. After using the app, our website is now faster than 86% of websites using the same test. Over 1100 photos and the app did some serious work. I definitely recommend for those with lots of photos. UPDATE

Update: It seems that our emails arrived in spam. Once they caught them, they were super responsive and addressed our problem with a very good solution. So we are now satisfied with everything and can safely recommend the App. Original message: We used the application a few months ago, and we must admit that it worked well for us. However, we wanted to use it again recently and needed help from the team. After 1 month and 3 emails, we are still waiting for an answer... We wanted to become paying customers, but this does not give us confidence in case of problems in the future.
