"cwebp" https://developers.google.com/speed/webp/docs/cwebp is a google thing like gif2webp--and downloads in the same collection with it--but it converts from png, jpeg, tiff, and webp.

Converting a gif2webp webp to webp with cwebp actually gets a tiny bit more compression:
 
"C:\downloaded\stuff\gif2webp\gif2webp.exe" -m 3 %1 -o "%~dpn1x.webp"
del %1
"C:\downloaded\stuff\gif2webp\cwebp.exe" -lossless -q 100 "%~dpn1x.webp" -o "%~dpn1.webp"
del "%~dpn1x.webp"

Messy but this handles both my tif and my gif (static only--cwebp doesn't do animated) conversions with one .bat file shortcut in the run: shell:sendto folder:

"C:\downloaded\stuff\gif2webp\gif2webp.exe" -m 3 %1 -o "%~dpn1x.webp"
"C:\downloaded\stuff\gif2webp\cwebp.exe" -lossless -q 100 %1 -o "%~dpn1.webp"
del %1
"C:\downloaded\stuff\gif2webp\cwebp.exe" -lossless -q 100 "%~dpn1x.webp" -o "%~dpn1.webp"
del "%~dpn1x.webp"

I already knew about gif2webp, which comes in the same download, but I didn't look at cwebp until I found it mentioned on compress-or-die.com as one of the suite of tools that site used, along with custom code, to achieve its out-of-sight levels of compression. Compress-or-die shuts down at the end of the month.
