Python uses Guetzli to batch compress image instance code

This article mainly introduces python's use of Guetzli to batch compress images. it describes in detail the open-source image compression tool Guetzli of Google, which is of great practical value. if you need it, you can refer to it.

Google is now open-source again. this time, it opened up Guetzli, an image algorithm tool. Guetzli, a cookie in Swiss German, is a JPEG encoder for digital and web images, allows you to produce smaller JPEG files for a faster online experience and maintain compatibility with the current browser, image processing applications, and JPEG standards. Google claims that Guetzli's creation of high-quality JPEG image files is 35% smaller than the current compression method.

Today, I played Guetzli, Google's open-source image compression tool, and found that the compression performance of a single image is good. I wrote a simple python script to compress images in batches.

Prerequisites

1. install Guetzli and use the command line tool.

2. python Environment

Simple code

#-*-Coding: UTF-8-*-import osdir_name = "your image folder" def get_file_name (file_dir): for root, dirs, files in OS. walk (file_dir): print (root) # print (dirs) # print (files) return filesfiles = get_file_name (dir_name) print (files) OS. chdir (dir_name) for file in files: cmd = "guetzli -- quality 85 -- verbose" + file + "" + file OS. system (cmd)

Effect

Before compression
