alainrafiki / compress_s3_images.py

Created February 8, 2016 00:58 — forked from rigoneri/compress_s3_images.py

Simple python code to compress (jpeg/png) images uploaded to S3. In this use case I want to compress down all images that are over 500 KB down to 80% quality which brings the images down to about 100KB. Feel free to muck with the values.

	#!/usr/bin/env python
	# -- coding: utf-8 --

	import sys

	from boto.s3.connection import S3Connection
	from cStringIO import StringIO
	from PIL import Image as pil

	AWS_KEY = '[AWS KEY HERE]'
