How to convert all images in a folder to webp format

Suppose there are some pictures in png format in a folder.

They all need to be converted to webp format. To do this, you need to enter the command in the terminal:

for file in *.png; do
  cwebp $file -o "${file%.*}.webp"
done

After that, the webp images will appear in the same folder.

If a folder contains images in different formats, for example png and jpg, then to convert them all to webp the command will be like this:

for file in *.{png,jpg}; do
  cwebp $file -o "${file%.*}.webp"
done
