Batch compression for PNG images
pytinypng is a batch image compression tool for optimizing thousands of images in png format. Under the hood it uses tinypng.com API to shrink png files.
- Optimized files are saving on disk keeping original directory structure
- Skip already optimized files.
Get Python 2.7 at http://www.python.org. If you’re running Linux or Mac OS X, you probably already have it installed.
If you are on Mac OS X or Linux, chances are that one of the following two commands will work for you:
$ sudo easy_install pytinypng
or even better:
$ sudo pip install pytinypng
Next, you should obtain the TinyPNG API key from the Developer API page page.
Run in terminal:
$ pytinypng /path/to/directory/with/png-images /path/to/output-directory --apikey <API_KEY>
You can hide api key from command line in:
- environment variable TINYPNG_APIKEY or TINYPNG_API_KEY
- inside file located in working directory under name tinypng.key
- or keep in your home directory as ~/.tinypng.key
