Please add support for uploading and displaying WebP images.
See https://developers.google.com/speed/webp

Most (perhaps all) modern browsers can display images which are in the relatively new WebP format. It has the advantage of being extremely efficient and still producing legible results. My personal experience has been that WebP compression is far more efficient than Google claims.

For example, here're the results for converting a 1920x1080 .PNG image using the default quality settings of ImageMagick v 7.0.10-27 (which is provided with Cygwin).
Code:
$ ls -l capture_0*
-rw-r--r--+ 1 selden None 565550 Sep 11 14:57 capture_002_11092021_143749.jpg
-rwxr-----+ 1 selden None 531230 Sep 11 14:37 capture_002_11092021_143749.png
-rw-r--r--+ 1 selden None 129462 Sep 11 14:57 capture_002_11092021_143749.webp
I was going to upload a zip of the images, but I keep getting the error message "invalid attachment". Oh, well, I'll rashly assume that the "powers that be" can make their own comparable tests.
