Compresssio - Optimize your Images to save storage space...

What I Built:

The above script uses TinyPNG's savvy lossy compression methods to reduce the document size of your JPG/PNG files. This is achieved by specifically decreasing the number of colors in the image, therefore lesser number of bytes are required to store the information. The impact of the script is nearly invisible but it makes an exceptionally enormous effect in file size of the image.

Image Comparison:

Setup (Windows):

  1. Install Python
  2. Clone this repository
git clone
Enter fullscreen mode Exit fullscreen mode
  1. Install, create and activate virtual environment. For instance we create a virtual environment named 'venv'.
pip install virtualenv
python -m virtualenv venv
Enter fullscreen mode Exit fullscreen mode
  1. Install dependencies
pip install -r requirements.txt
Enter fullscreen mode Exit fullscreen mode

Yes, there can be a feature where you can select the compression ratio as per your preferences for the image but for now it's not implemented in this Script. So wait till further updates.
