image-resize

Batch resize images for web use by processing folders or individual files via the command line. This tool reads JPEG, PNG, and WebP files, applies target dimensions, and saves compressed results to a specified output directory.

Preserve aspect ratio when resizing images by omitting the height parameter; the tool calculates the proportional height automatically. Providing both width and height applies exact dimensions instead.

Pillow supports compressing PNG and WebP files in bulk by reading source directories and writing optimized images to disk. The script handles batch processing natively to prepare images for mobile platforms.

Compress images for mobile use without losing dimensions by specifying a target width while omitting height to maintain the aspect ratio. This ensures the image scales proportionally without distortion.

You need Python and the Pillow library installed to batch resize JPEG files. The script uses Pillow to process the images and write the resized outputs directly to your designated output directory.
