Answer 1

Foremost I recommend to install imagick package on your Ubuntu distro.

If you don't have it installed run sudo apt install imagemagick command. Open the folder which you have subfolders containing files with the extensions you want to convert on your terminal.

After that run following command on your terminal:

find . -type f -name "*.png" -exec mogrify -format webp {}  \; -print && find . -type f -name "*.jpg" -exec mogrify -format webp {}  \; -print && find . -type f -name "*.jpeg" -exec mogrify -format webp {}  \; -print

You can also combine all above commands in single expression using regex:

find . -type f -regex ".*\.\(jpg\|jpeg\|png\)" -exec mogrify -format webp {}  \; -print

To remove the leftovers (original files), run following command afterwards:

find . -type f -regex ".*\.\(jpg\|jpeg\|png\)" -exec rm {}  \; -print
