Python batch converts images from png format to WebP format

Achieve the effect

Convert 1000 .png pictures located in the /img directory into .webp format and stored in the img_webp folder.

Source picture directory

Target picture directory

For batch generation of 1000 pictures, you can refer to this article:Use Python batch generates images of any size

Implementation example

##

import glob
import os
import threading

from PIL import Image


def create_image(infile, index):
  os.path.splitext(infile)
  im = Image.open(infile)
  im.save("img_webp/webp_" + str(index) + ".webp", "WEBP")


def start():
  index = 0
  for infile in glob.glob("img/*.png"):
    t = threading.Thread(target=create_image, args=(infile, index,))
    t.start()
    t.join()
    index += 1


if __name__ == "__main__":
  start()

Note: This project needs to reference the PIL library.

Considering that it is a large number of linearly intensive operations, multi-thread concurrency is used. When creating a thread object through

threading.Thread(), please note that the args parameter only accepts ancestors.

Here, we use the

Image.open() function to open the image.

Finally call the

save("img_webp/webp_" + str(index) + ".webp", "WEBP") method to write to the specified location in the specified format. The format parameter is the target format.

Okay, this article is basically over. Have you all learned it? I hope it will be of some help to everyone's study and work.
