  • Why convert images to WebP?

    Nowadays, websites are overloaded with images and media files of all kinds. The site owner wants to please the visitor but often doesn’t realize that he may actually be unwittingly contributing to the user leaving the site faster. Why? Because pages that are too rich in images and media files simply load slower. And as a result, it is not uncommon for a user to leave the site before it loads.

    A possible solution to this issue is to prevent long page load times. This can be done very easily – by converting images to WebP. The weight of images converted to WebP format is on average 50% less than the original images.

    Another point in favor of having images compressed into Webp format is its high percentage of browser compatibility.

    Files compressed to WebP will almost certainly be supported by your site user’s browser, as this format has great support (albeit not 100%). According to, currently approx. 97% of browsers support the WebP image format. This is an important point, as currently not all image formats can boast such high support for browsers.

    WordPress WebP plugin – how to choose the right one?

    WordPress does not support automatically converting images to WebP format. This is because if this were the case, images would not be supported on a certain fraction of devices. In the present situation, this can be prevented by using a plugin to convert images to WebP. It is up to the user to decide whether the images on their WordPress site should be converted to WebP or not. All you will have to do is to use a WebP WordPress plugin that will do all the work.

    • Simplicity of use – let the plugin do everything for you! Ideally, all would happen with just a click of the mouse. Bet on a WebP plugin that is ready out of the box.
    • Guarantee to compress images to half their size or less – this way your site will load faster.
    • Versatility – It should not matter if the image displays as an img HTML tag or as a background-image.
