Batch convert images to grayscale

To batch convert images to grayscale, you can use Python with the Pillow library, which makes it simple and efficient. Below is a Python script that takes all images from a source folder, converts them to grayscale, and saves them to a destination folder.

Requirements:

• Python installed on your machine

• Pillow library (pip install Pillow)

Python Script:

python
CopyEdit
import os
from PIL import Image

# Set source and destination directories
source_dir = 'path/to/source/folder'
dest_dir = 'path/to/destination/folder'

# Create destination directory if it doesn't exist
os.makedirs(dest_dir, exist_ok=True)

# Loop through all files in the source directory
for filename in os.listdir(source_dir):
    if filename.lower().endswith(('.png', '.jpg', '.jpeg', '.bmp', '.gif', '.tiff')):
        img_path = os.path.join(source_dir, filename)
        img = Image.open(img_path).convert('L')  # Convert to grayscale
        save_path = os.path.join(dest_dir, filename)
        img.save(save_path)

print("Batch conversion complete.")

Notes:

• Replace 'path/to/source/folder' and 'path/to/destination/folder' with your actual folder paths.

• This script supports common image formats.

• .convert('L') is the key function to turn an image grayscale.

Let me know if you want this done with a GUI, shell script, or another programming language.
