how to convert .bmp images to .png

this is a part of my code, but it doesn’t convert images to png

First install pillow:

pip install pillow

Then run this script on the folder with the .bmp files:

from PIL import Image
import glob
import os

from pathlib import Path

current_dir = Path('.').resolve()

out_dir = current_dir / "converted"
os.mkdir(out_dir)
cnt = 0

for img in glob.glob(str(current_dir / "*.bmp")):
    filename = Path(img).stem
    Image.open(img).save(str(out_dir / f'{filename}.png'))

You can simply use Pillow library. Use glob to read the .bmp images from a folder, Pillow to resize and save as .png. 

from PIL import Image
import glob
import os

out_dir = ''
cnt = 0
for img in glob.glob('path/to/images/*.bmp'):
    Image.open(img).resize((300,300)).save(os.path.join(out_dir, str(cnt) + '.png'))
    cnt += 1
