Optimize your images for web and local storage

What does optimizer do?

The script uses TinyPNG smart lossy compression techniques to reduce the file size of your JPG/PNG files. By selectively decreasing the number of colors in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large difference in file size.

Setup

1. Download and install the latest version of Python
2. Clone this repo

git clone https://github.com/kerogenesis/image-optimizer.git

3. Create and activate virtual environment

python3.9 -m venv venv
source venv/bin/activate

4. Install dependencies

pip install -r requirements.txt

Initial setting

1. Open settings.py in any text editor.
2. Add a key from tinypng.com/developers to the API_KEY field.
3. In the USER_INPUT_PATH field add a directory path with raw images.
4. In the USER_OUTPUT_PATH field add the directory path with compressed files.

You can also select the option to delete raw images after compression.

Easy way to use

Linux/macOS

Create сompression.sh file with:

#!/usr/bin/env bash
source path/to/venv/bin/activate && python3.9 path/to/image_optimizer.py

Give this file permission to execute:

chmod +x сompression.sh

Move it to any place (e.g. desktop) and run it.

Windows

Create compression.bat file with:

@echo off
cmd /c "path\to\venv\Scripts\python.exe path\to\image_optimizer.py"

Move it to any place (e.g. desktop) and run it.

Important note

Remember the limit of 500 images per month on the free plan. You can change this at tinypng.com/dashboard/api
