This contribution adds a Pillow-based helper for batch image conversion.

• Convert JPG, PNG, BMP, WEBP, TIFF, and GIF files in batch.
• Optionally resize images to a fixed canvas.
• Preserve RGBA transparency for formats that support it.
• Fill resized images with white or transparent background.
• Create animated GIF files with configurable frame duration.

pip install Pillow

Convert all images in a folder to PNG:

python batch_image_converter.py convert ./images ./output --format png

Convert to WEBP and resize to an 800x600 canvas:

python batch_image_converter.py convert ./images ./output --format webp --size 800x600

Create an animated GIF:

python batch_image_converter.py gif ./images ./output/demo.gif --duration 300

from batch_image_converter import convert_images, create_gif

convert_images(
    input_path="./images",
    output_dir="./output",
    output_format="png",
    size=(800, 600),
    background="transparent",
)

create_gif(
    input_path="./images",
    output_file="./output/demo.gif",
    duration=300,
    size=(800, 600),
)
