Introduction
WebP is an image format developed by Google in 2010. It is mainly used in the network environment and provides lossless and lossy compression. Website developers can use WebP to create images with smaller size and richer details, so as to speed up the opening speed of the website and improve the user experience of visitors. In the future, the pictures on this site will also use WebP format, which can greatly save the disk space of the server .
Practical
Here we use the pillow library to convert the image format, first install it through pip
pip install -U pillow
The principle of implementation is actually very simple. Use pillow to open the original file, usually png and jpg , and then save it in webp format. See the sample code below
from pathlib import Path from PIL import Image def convert_to_webp(source): """Convert image to webp. Args: source (pathlib.Path): Path to source image Returns: pathlib.Path: path to new image """ destination = source.with_suffix(".webp") image = Image.open(source) image.save(destination, format="webp") return destination if __name__ == '__main__': paths = Path("C:\\Users\\\Administrator\\Desktop\\images").glob("**/*.png") for path in paths: webp_path = convert_to_webp(path) print(webp_path)
It can be seen that the file size gap between the original png image and the processed webp is still quite large
