How to convert to WebP all the images on the Ubercart

Why is it worth using WebP for Ubercart?

Using Webp solves the "Serve images in next-gen formats" issue in Google Pagespeed Insights.

In short, WebP compresses the file better, all other things being equal, than older formats (png and jpeg) - which means it takes up less space on the hosting and loads faster in the browser when viewing the page.

The implementation of WebP is actively promoted by Google - they provide such statistics:

• WebP compresses images losslessly 26% better than PNG.
• WebP compresses lossy images better than JPEG by 25-34% with the same structural similarity index (SSIM)
• WebP supports lossless transparency (known as alpha) with a size increase of only 22%.

If the visitor’s browser does not support WebP, then the CDN will return the old format (png / jpeg), but compressed (optimized for the Web)

What is image compression

Image optimization is special processing of a graphic file in order to minimize its size without loss of visual quality.

To carry out this procedure, there are a large number of fairly complex algorithms. However, they are all based on the same basis - all the service data there (for example, the name of the program that stores the file, etc.) must be removed from the graphic file, and also, using special programs, merge / smooth similar colors.

As a result, we get the same image, which visually has not changed. However, the volume (weight) of this file in bytes will be much less than the original. If this processing is carried out correctly, the image file can be reduced to 98% without losing image quality.

This means that the pictures on the pages of the site will be loaded many times faster after the optimization.

What will optimize images for your site

• Save disk space.
• Speed ​​up page loading.
• Minimum server load.
• Increase conversion.
• Better site ranking for search results.

It has been proven that website acceleration can improve behavioral factors, as well as increase website conversion (increase sales). The longer the page of the site loads, the fewer customers will be able to perform certain target actions there. If your site on the Internet will not work fast enough, you have every chance to miss your potential income. Acceleration of the online resource will provide an opportunity to improve the conversion and due to this significantly increase revenue and attract more customers.

How can optimizing images for Ubercart speed up a site?

 

A page of any site most often consists of:

• images;
• html-code (text content, layout, markup);
• video;
• javascript scripts with logic running from the browser;
• css files with page styles.

 

Such an item as an image occupies most of the entire volume on the site’s pages and is the “heaviest” part of the pages. Reduction (optimization) of images will undoubtedly significantly make it faster to download any online resource.

 

Accordingly, if you change (down) the size of the images, all pages of the site will start loading much faster.

Compressing the images on the site will make it possible to reduce their volume to 75-98%, without losing their visual quality.
