AVIF is the new kid in town when it comes to image codecs. Since it's still brand-new, support for this technology by operating systems, tools, and also browsers is still somewhat limited.
However, with JaJuMa Ultimate Image Optimizer you now have the tool at hand to make use of this impressive improvement for images in your Magento 2 store.
And no worries, AVIF support by our extension comes with no downsides for your customers that use Browsers with no AVIF support. Each Browser will show the best image format depending on its capabilities!

Don't wait, there is no excuse for not getting your Magento 2 store images up-to-date and ready for the future. AVIF is being developed by the Alliance for Open Media, which is backed by numerous big technology players, such as Google, Mozilla, Apple, Facebook, Microsoft, Netflix, and Amazon, just to name a few. With this strong and impressive backing and seeing how superior AVIF is over its alternatives, there is no doubt there will be wider adoption and use of this technology in the near future!


Hard to imagine running a webpage without using WebP.
With its superior compression algorithm compared to .jpg or .png image files and by now being supported by all major browsers it's an improvement for faster image loading nobody wants to miss.
Even more so since it's super easy to add using our extension without any risk or extra costs.
If you are not familiar with WebP yet, please check the links below for further info and also quality comparisons.

Lazy Loading

By enabling lazy loading, images on your site will be only loaded while visible within the viewport / when the user is scrolling down.
This will speed up page load times for your customers, save bandwidth for your customers as well as for you.
In other words, lazy loading is an improvement for user experience on your site and at the same time helps also improving your SEO rankings.
Of course, with our extension, you have the possibility to exclude certain images from lazy loading, which is recommended e. g. for banner images or "hero"-images above-the-fold.
It is also possible for you to upload a custom loading icon to match your design and look'n'feel of your site - or simply use a transparent/invisible icon provided with the extension.

High-Resolution ("Retina") Images 

Many customers visit your store using so-called "High-Resolution" or "Retina" displays. These displays have a higher pixel-density which allows showing images and text with much more detail, sharper, and less "blurry" than traditional displays.
By adding High-Resolution versions for your product images with our Ultimate Image Optimizer extension you can now make use of this technology.
Impress your customers with higher quality and crystal clear images and do not worry anymore about the tiny details in your product images getting lost in the blur of low-quality images.
Give your conversion rate a real boost by convincing your customers with impressive images of your products that are a joy to look at and show off every tiny detail.

Image Optimization Status & Statistics

Image optimization status & statistics data can be updated regularly via cron job or manually from the Backend and provides a clear and up-to-date overview in the Backend of which images have been optimized (= converted to AVIF, WebP & High-Res versions created depending on your configuration) and which images are still pending conversion/optimization.

For each image converted to AVIF/WebP, you can see the file sizes and savings realized in Image Optimization Status screen.
