Change Image Format

➤ Single conversion​

Change the format of an image, the available formats are png jpeg jpg webp
You can also rename and convert a single image without the -f flag (second example)

gowall convert ~/Pictures/img.webp -f png
gowall convert ~/Pictures/img.webp --output ~/Pictures/gowall/renamed.png

The above converts a .webp over to .png

➤ Batch conversion​

gowall convert --batch img1.png,img2.png -f webp

➤ Directory conversion​

Converts all the images under ~/Pictures/Dir into .webp and saves them to ~/NewFolder

gowall convert --dir ~/Pictures/Dir -f webp --output ~/NewFolder
gowall convert --dir ~/Pictures/Dir -f webp # saves to the default dir
