Batch rename image files by resolution

To batch rename image files by their resolution (e.g., width x height), you can use a script to extract the resolution of each image and rename the files accordingly. Below is a Python script using the Pillow library:

✅ Python Script: Rename Images by Resolution

python
CopyEdit
import os
from PIL import Image

# Set the directory containing your images
image_folder = 'path/to/your/images'

# Supported image file extensions
image_extensions = ['.jpg', '.jpeg', '.png', '.bmp', '.gif', '.tiff']

# Rename files
for filename in os.listdir(image_folder):
    file_path = os.path.join(image_folder, filename)
    base, ext = os.path.splitext(filename)

    if ext.lower() in image_extensions:
        try:
            with Image.open(file_path) as img:
                width, height = img.size
                new_name = f"{width}x{height}_{base}{ext}"
                new_path = os.path.join(image_folder, new_name)

                # Avoid overwriting existing files
                if not os.path.exists(new_path):
                    os.rename(file_path, new_path)
                    print(f"Renamed: {filename} -> {new_name}")
                else:
                    print(f"Skipped (exists): {new_name}")
        except Exception as e:
            print(f"Error processing {filename}: {e}")

🔧 Notes:

• Replace path/to/your/images with your actual directory.

• It renames files to format like 1920x1080_oldfilename.jpg.

• Avoids overwriting files with same name.

Let me know if you want the new names to be just resolution (e.g., 1920x1080.jpg), numbered (e.g., image_1920x1080_01.jpg), or if you’re working in Windows and want a PowerShell or batch script instead.
