i found the script-fu menu.
You mean for 100 quality .webp from Gimp = 1.66 MB versus from IM = 5.38 MB (much larger than Gimp)
Probably a bug with IM. Using the convertor binary from Google cweb a 100 quality .webp is 1.7 MB edit: binaries here: https://developers.google.com/speed/webp/download
For values other than 100 Gimp and IM are close in file size.
