PyGuetzli
=========

|Github| |Discord| |PYPI Version| |Build Status| |License|

**PyGuetzli** is a Python binding for Google’s
`Guetzli <https://github.com/google/guetzli>`__ library.

Description of **Guetzli** from official’s repo:

   Guetzli is a JPEG encoder that aims for excellent compression density
   at high visual quality. Guetzli-generated images are typically 20-30%
   smaller than images of equivalent quality generated by libjpeg.
   Guetzli generates only sequential (nonprogressive) JPEGs due to
   faster decompression speeds they offer.

Usage Example
-------------

.. code-block:: python

   import pyguetzli

   input_jpeg = open("./test/image.jpg", "rb").read()
   optimized_jpeg = pyguetzli.process_jpeg_bytes(input_jpeg)

   output = open("./optimized.jpg", "wb")
   output.write(optimized_jpeg)
