将多个文件从JPG转换为PNG

Question

I'm trying to convert multiple JPG files into PNG files. I'm able to do it for a single file but the loop doesn't seem to work for multiple files. Could you please help with that? I'm sharing my code below:

from PIL import Image

img = Image.open('./image.jpg')

img.save('new_image.png','png')

print('All done!')

Answer 1

You can try this -

from PIL import Image
import glob

counter = 0
for image in glob.glob("./*.jpg"):
    counter = counter + 1
    img = Image.open(image)
    img.save(str(counter)+'new_image.png','png')

Answer 2

#So the following code worked. Sorry for the formatting, I'm just beginning to learn!

from PIL import Image import glob import os

directory = r'C:\Users\Umar Iqbal\Desktop\newfolder' #this is where we will save our converted images

for image in glob.glob('./*.jpg'): img = Image.open(image)

clean_name = os.path.splitext(image)[0] #if we don't use this, we get jpg in the file's name

img.save(f'{directory}{clean_name}.png', 'png') #this allows us to save the new images in the directory
