Imagemagick batch convert to webp, without making an animation

I want to convert PNGs to webp, for that I use :

convert *.png -quality 90% -set filename:basename "%[basename]" "optim/%[filename:basename]".webp

Instead of writing one webp per png, I get one webp file with all the images as an animation.

I'm pretty sure I used a similar command in the past with success, I'm now using ImageMagick 7.0.8-68 on Macos.

What should I add to get individual WEBPs instead of an animation?

Edit: here's a full test case, ImageMagick installed through Homebrew, version 7.0.9-5 Q16 x86_64 2019-11-18

Create multiple PNGs :

for i in {1..9}; do convert -background black -fill grey -font impact -size 320x240 -pointsize 96 -gravity center label:$i out-$i.png; done

then attempt to convert to individual WEBPs:

convert *.png -quality 90% -set filename:basename "%[basename]" "optim/%[filename:basename]".webp

Result here is one WEBP file containing all images as an animation.

2Your command fails for me because the folder optim did not exist. When the folder optim does exist it converts and does not create an animation. – somebadhat – 2019-11-17T17:58:28.190
