In 2010, Google introduced the WebP image format, a new format for images that creates images up to 45% smaller in size than PNG, for similar quality.
Google's WebP image format is apparently supported by Google Chrome and browsers powered by Chromium, such as Opera. It has not been, as you can easily imagine, particularly well-received by other browser manufacturers due to the competition between them. To date, no browser, except Chrome and Opera, can "read" and display WebP images. Major image viewing and editing programs have supported it for a long time.
You can compare the photo in this article, which is essentially a screenshot of the latest version of Firefox 62.0.3, where it cannot display WebP images and instead only displays their tags (right).
But with the new Windows 10 October 2018 Update (the one that some people lost their files in), Microsoft Edge browser supports the WebP image format. It seems that Mozilla will also embrace Google's technology. According to CNET, Mozilla's Firefox browser will finally support Google's WebP image format.
Specifically, the news that CNET brings us is that Mozilla is moving forward with supporting the WebP format for Firefox that will run on desktop and Android. It clearly states that Firefox that will run on iOS will not support WebP.
We are therefore waiting to see developments on the subject. We are interested because smaller photos, with the same quality, ensure a reduction in bandwidth, less traffic on networks and therefore a faster internet.
