Build a Batch Image Resizer with Python
Level: Beginner
Build a Batch Image Resizer
Your task for today is to create a script that automatically resizes down all images in a folder, perfect for optimizing images for web use or reducing file sizes.
Project Task
Create a batch image resizer that:
Uses the Pillow (PIL) library to work with images
Scans the /images folder for all image files
Resizes each image to less than 50% of its original dimensions
Saves the resized images to a /resized_images folder
Processes multiple image formats (PNG, JPG, JPEG)
Displays progress messages for each image processed
Creates the output folder automatically if it doesn’t exist
This project gives you hands-on practice with file operations, directory handling, batch processing, and image manipulation — essential skills for automating repetitive tasks.
Expected Output
The script should load a directory of images such as this one:
(You can download these images here)
After the script runs the image’s size should be smaller:
