Features

• Parse command line parameters: Especially the -s parameter, which supports formats such as 100k and 80%. When parsing parameters, determine whether the size is fixed or a percentage, and execute different logic based on the parameters.
• Traverse files: Use os.walk to traverse all files in the folder, and only process images such as .jpeg/.jpeg/.png.
• Adjust image size: Use the Pillow library to adjust the image size. If the -f/--format format is not specified, keep the original format.

Usage

pip install -r requirements.txt
python resize_images.py -i . -o /tmp/ -s 100k -f jpg
python resize_images.py -i input.jpg -o output.jpg -s 100k
python resize_images.py -i input.jpg -o output.jpg -s 50%
python resize_images.py -i input_dir -o output_dir -s 100k
