Comment (by adamsilverstein):

 > for the specific purpose of generating thumbnails in a widely supported
 format today, WebP is definitely the right choice, so there's no reason to
 start a long discussion, agreed.

 Thanks for the feedback and raising the specific limitations-  and for the
 JPEG XL ticket @atjn!


 > Regarding CPU/memory requirements, webp generally uses about 40% less
 memory than jpeg encoding, but is 2x to 3x more cpu intensive.

 Very interesting @marylauc! Is the tradeoff intentional, eg. has WebP been
 optimized to reduce memory usage at the expense of CPU use?

 I wonder how hosts would feel about this potential impact? cc:
 @mikeschroder.


 > These images would typically be encoded losslessly anyway (using png or
 webp lossless).

 This brings up a good point, so far we have thought mostly about jpgs.  In
 addition, when users upload a lossless format image, we should take
 advantage of WebP lossless.
