The day I installed this app was the day my website went insane. I had multiple issues right out of the gate with this one. I ran the free speed optimizer and also used their image tool to optimize 100 images. My thinking was I would test the free version, and if it worked I would pay for monthly optimizations. Test failed.
The first, and biggest problem, was that the app made a duplicate version of my website. I did not realize right away, but the "optimized" theme was downgraded from Dawn 7.0 to a modified Dawn 4.0 that was unable to update. And not just the theme it duplicated....ALL my backups were suddenly Dawn 4.0. My website is less than a year old, Dawn 4.0 was never previously installed on my site, ever.
I also had multiple product images that simply vanished and needed to be re-uploaded. On mobile, my product image swipe quit working. Even though it would say 1/4 images....It would only show one on mobile. I also had two "sale" icons on the products that were on sale, and one was half way off the screen so it was definitely causing glitches. Random icons on my website also disappeared and my website was overall glitchy. The optimizer tool got my page speed from a 28 to a 41 right away. However, the next day I was down to a 21 page speed and my website was simply not working.
I decided to try to update my website to Dawn 9.0 since 4.0 was such an old version I figured that could be part of the problem...But no, the theme was modified and could not be updated. I had to download a fresh version of my theme. None of my page templates would transfer....I would have to completely re-design my website.
So I got in touch with Shopify support hoping for an easier solution, who told me whatever the optimizer did to my theme to remove the "unused" javascrips and css, did something to my theme files. They suggested I contact the app developer support and ask for whatever they did to my website to be rolled back or removed.
The Swift app developers got back to me quickly and looked into my issue, which I was happy about. However, they came back and told me it was "impossible" that my themes were downgraded to 4.0, and that it was "unreasonable" that I did not notice immediately (Do you check what version of theme you're using every day?) They offered zero solution, and told me to go back to Shopify with their email. So I did.
Shopify support agreed that the email from the Swift app support was incredibly unhelpful and basically dodging responsibility. I spent a whopping four hours with Shopify support, and spoke to multiple people as they sent my case up the ranks to figure out why my site wouldn't update, why there were so many glitches, and why none of my page templates would transfer to my fresh Dawn 9.0 theme download from the modified 4.0 themes. After all that time, it was finally suggested that I just rebuild my page themes and redesign my website. We had to delete all my old backups that were corrupted by the Swift Page Speed Optimizer tool and start over. Devastating.
After removing all of the theme backups that were corrupted and starting on a fresh theme download....My google page speed went from a 21 to a 64. Removing whatever the Swift app did, fixed everything. My website now runs flawlessly with a vastly improved speed score. In hindsight, I should have just upgraded to 9.0 before trying this app.
I asked the Shopify support rep how a Shopify app from the Shopify App Store could so severely damage my website files...and they told me that Shopify has no control over what apps are on the app store and to use caution. They told me the best thing I can do is to leave a detailed review of what happened so other users may not have this problem. So here I am .
I give one star for the support team responding to me, thanks for the response, as unhelpful as it was. Otherwise, I would avoid this app, or any app, that automatically alters theme files. Zero stars.

It technically increased the speed but it creates a bunch of issues with our site and conflicted with some apps. Weird bugs showed up and they calmed it on the theme even though the theme was working perfectly before. Hours of explaining and debugging but it was never perfect. They operate from Vietnam as well. Their code seemed wonky and causing more trouble than goods. Uninstalling the app. I wasted tens of hours on this. Giant fail.

Deleted the app, and not only does their code stay, but it also took down our website, on every single theme. Sent them an email but we never got anything back. As long as this wont get fixed, I'm leaving this 1 star review.

I would not recommend using their "experts" to boost your page speed. Paid good money and my store still has low score of 45 on Google page speed, 30 in Swift app, and 30 on shopify. Not happy that I didn't get what was expected.

The app automatically compressed 3000 images of my products, and when I found out it was impossible to recover them. Contacted shopify support and couldn't recover it.
Hi there,
I am Seri from Swift - Page Speed Optimizer Support Team.
Firstly, I sincerely apologize for any inconvenience caused to you when experiencing our app.
Regarding your concern, after compressing your images, your original images will be replaced by the new compressed ones. Those original images are stored on Shopify system then and after 30 days if you do not revert the original images, those images will be deleted forever. It is the limit of Shopify and we are still researching further to improve on this matter.
Therefore, for the best practice, please kindly review your images carefully right after you optimize them then if there's any problem with the images, you can revert them immediately without any issues.
If you still have any further concern, please don't hesitate to contact us via email support@perfectapps.io. We are always willing to help.
Kind regards,
Seri

I'm really disappointed with the service I've received. I paid $150 to have my theme optimised. It was faster but product images wouldn't load which is kind of essential in ecommerce! I asked for support but the first response blamed me for switching back to my original theme (I mean, I couldn't exactly leave the theme without functioning images up) and then they ghosted me when I followed up. So they were super keen to take my money but suddenly nowhere to be seen when I ask for them to fix my broken theme/refund my money. I feel really ripped off.
Hello there,
I am Maria from Swift ‑ Page Speed Optimizer Support Team. Firstly, I sincerely apology for any inconvenience caused to you.
As relating to your problem, we have received your message some weeks before and our support have replied back right away to assist you on the problem but we did not receive any response from you yet. We checked and fixed the problem with image loading already and asked you to check again on the new optimize theme but seems that you still have not taken a look yet. We have then sent you many follow up emails to ask more information about the issue in order to assist you better but you just kept silence and we honestly do not know how to support you in the right way.
I have sent you a follow up email again to support you sort the problem out. Please kindly check our message and reply back so that we would know the issue and help you out as soon as possible.
Kind regards,
Maria
This app is terrible!! Do not install !!
Half our pictures are now blurry. Even after removing code pictures still look terrible. It’s unexceptionable and with offset business hours, the window of communication is very small, so this might take days to correct, meanwhile we are sitting ducks. We went in to get a faster website and ended up with a website not functioning at all

I Do Not Recommend This App. The First Day I Downloaded This App I Used It, and it Requested to optimize and speed up my theme so I let it. It Completely Destroyed My Theme And I Had To Use A Backup That Some People May Not Have. They ended up giving me a replacement 5 days later which was slower than the original theme. The Support Isn't even online when there hours say they are. Not Worth the download and definitely not worth the price, I had there premium package going through all this.
