About Minifier SEO Image Optimizer

Did you know that people tend to leave a website if it doesn’t load in 3 seconds?

Frightening! Google says that as page load time goes from:

  • 1s to 3s the probability of bounce increases 32%
  • 1s to 5s the probability of bounce increases 90%
  • 1s to 6s the probability of bounce increases 106%
  • 1s to 10s the probability of bounce increases 123%


Eye-opening, right?

Even worse is that the stats are from 2018 and our attention span shortens every year. This could mean, that if your store is overweight, you’re losing money right now.

No worries, we can help!

We analysed and optimised over 32 million images helping thousands of stores go from fat to fit. Industry-leading algorithm we use is trusted by brands like Tesla, Microsoft, Dell, Nvidia, Kaspersky.

We wrapped the algorithm and other powerful features into Minifier - image compression, alt tag and file name optimisation app.

Minifier compresses images, optimise alt tags and file names so that your store is much lighter, loads faster and is loved by Google more.

The app does it in 3 steps and here’s what you can expect if you’ll add Minifier to your shop.

  • Minifier will count and analyse images. It will ask you to select your optimisation preferences. That’s free.
  • Minifier’s will download images to our cloud storage and run algorithm. Magic happens here.
  • Then, you decide if you like compressed images, generated alt-tags and file names. Because you're the boss.

We know how much quality matters! Even the more aggressive Minifier’s lossy compression will preserve image quality while saving up to 80% of space. If you’re still concerned about lower image quality, know that your original files are saved on our server for a 30 days and are ready to be reverted anytime.

It’s so simple but that’s not all…

Auto-optimisation set it and forget it plan will optimise images for a $0.004 per image without distracting you from daily goals.

Set your optimisation preferences once and leave Minifier to do the work. New images will be optimised once a week and we'll send you optimisation results in an easily digestible email.

If I could give this app zero stars I would. Customer service Zero!!! Got this app to try over all of my file names, not possible. All this does is barely compress files. Piece of junk, don't bother.

Hi Justin! System shows that you didn't select an option to optimize file names when using auto-optimization maybe that's why Minifier didn't touch them. Anyway, I emailed you on how we can fix that, just let me know if I can proceed and we'll get the problem solved in no time!


Great and quick support. App does what it says! I like that I can choose between two different types of optimisation to fit my needs , I would definitely recommend this app.

Thank you, Premek! I'm glad that reverting optimization allowed you to try another compression method.


Most intuitive of the lot. I would definitely recommend this to others looking for a great starting point for image optimizers.

Hi UniquiTee! Yes, UX is so important and most of the apps do not even invest in UX designer. Thanks for your feedback!
