Script to convert all the `JPEG` images to the `WEBP` format in your Android project

convert-to-webp.sh

# `-lossless` not used to give support for Android 4.0+

# Make sure cwebp is installed.
if ! type "cwebp" > /dev/null; then
    echo "Please install cwebp to continue:"
    echo "brew install webp"
    exit 1
fi

# Convert all the images in the project that are not converted.
for f in $(find . -name "*.jpg")
  do
    echo "Converting $f"
    oldSize=$(du -h $f)
    cwebp -pass 10 -m 6 -mt -jpeg_like -q 60 $f -o "${f/%.jpg/.webp}" &>/dev/null
    newSize=$(du -h ${f/%.jpg/.webp})
    echo "The image was compressed: $oldSize -> $newSize"
    rm $f
done

Do not know how to Install cwebp on phone. See Linux and windows. Nothing for Android. Assuming no root needed? Tasker can launch the ss file. I cannot see how to set android permissions to execute for file. Extensions don't matter in Linux. Compile has never worked for me outside of ahk or basic. Never enough help for c or Linux compile.

Need apk and tasker instructions for the ss file.

Is there a way to convert the jpg, png files according to the android api, and the format of png, like is has alpha channel, just like the Android Studio do.
