Python Image Compress

compressMe.py

#run this in any directory add -v for verbose 
#get Pillow (fork of PIL) from pip before running --> pip install Pillow

import os
import sys
from PIL import Image

def compressMe(file, verbose=False):
	filepath = os.path.join(os.getcwd(), file)
	oldsize = os.stat(filepath).st_size
	picture = Image.open(filepath)
	dim = picture.size
	
	#set quality= to the preferred quality. 
	#I found that 85 has no difference in my 6-10mb files and that 65 is the lowest reasonable number
	picture.save("Compressed_"+file,"JPEG",optimize=True,quality=85) 
	
	newsize = os.stat(os.path.join(os.getcwd(),"Compressed_"+file)).st_size
	percent = (oldsize-newsize)/float(oldsize)*100
	if (verbose):
		print "File compressed from {0} to {1} or {2}%".format(oldsize,newsize,percent)
	return percent

	tot = 0
	num = 0
	for file in os.listdir(pwd):

Just change print statements to print() and works out of box! Thanks

Does not work for me. The compressMe function turns a 397K picture into a 2.3M one...

I'd try and play with the picture.save("Compressed_"+file,"JPEG",optimize=True,quality=85) settings I used this for very very large files (10mb) avg so doubt that quality setting would still apply for an already fairly compressed jpg.

I can indeed confirm that this works.

I am experiencing similar behavior

Does not work for a 7mb PNG
