This Python script compresses PNG images in a specified directory by converting them to JPEG format. It handles transparency by compositing images onto a white background, ensuring the converted images maintain visual quality while potentially reducing file size.
Before running the script, install the required Python libraries. You can install them using the provided requirements.txt file:
pip install -r requirements.txt
Ensure you have Python 3.6 or newer installed on your system. Clone this repository or download the script and requirements.txt file. Install the required libraries as mentioned above. To use the script, run it from the command line with the desired options:
python main.py [options]
-i,--input <directory>: Specify the input folder containing PNG images to process.-o,--output <directory>: Specify the output folder where the resulting JPEG images will be saved. The folder will be created if it doesn't exist.-q,--quality <integer>: Set the JPEG quality for the conversion (default is 80). Higher values result in better image quality with larger file sizes.-h,--help: Display help information showing all command-line options.
To convert PNG images from the source_images folder and save the JPEG images to the converted_images folder with a quality setting of 80, run:
python main.py -i source_images -o converted_images -q 80
