Convert webp to png

 

Any file to PNG

$ sudo apt install webp

$ for i in *.webp; do name=`echo "$i" | cut -d'.' -f1`; echo "$name"; dwebp "$i"

Add to Nautilus Script

fincahuanaco@pisces:~/.local/share/nautilus/scripts$ cat toPNG   
dwebp $1 -o "$1.png" 
rm $1


$chmod +x toPNG 

Updated to Selection to PNG (2023)
