I've noticed in the past week that images uploaded to wikis as PNGs and JPGs are being converted to WebP.

For example, if you click on the image at File:Domain migration results chart.png, it tries to save as a .webp file. (Note, however, that if you click the original file link on the image description page, you will still get the native file format — png — and it renames the file to "image").

Did I miss a Staff Blog post about this? Why was this done and what are the benefits?
