  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

    For more information about Imagick usage you can find on their official site and about mogrify here.
