Sorry did not see that as my ISP outsourced spam filtering to some outfit which bounces mailing list messages, triggering confirm membership messages to me every few days from various lists. > https://caniuse.com/webp > It seems covered by most of recent browsers Everything from our Qupzilla and newer, but excluding all IE (unsupported), and our Midori and Epiphany. One issue I found is that our DocBook 4 does not support webp, so there is currently no support for webp images in generated docs from cygwin-apps/cygwin-x-doc, so no value in converting, unless we want to script an update to the image sources in the *generated* html. This affects only cygwin-htdocs/xfree/docs/ug/figures/ ~640KB reduced to ~195KB in the attached image summary log. Directory summary totals are grouped at the bottom to show overall numbers. It also looks like cygwin-htdocs/xfree/docs/ug/stylesheet-images/ and cygwin-htdocs/xfree/images/ are not referenced anywhere so can be rm'ed: checked with egrep -iR 'png|gif|bmp' cygwin-htdocs/. So the net effect would be a reduction in image sizes from <4MB to <1MB. -- Take care.
