- description: Batch-resize images for web (WebP at 1920/1200/400px), social (center-cropped for Instagram, Twitter/X, LinkedIn), slides (JPEG at 1024×768 and 1920×1080), and print (300 DPI JPEG at ARCH A/B/C). Use when the user asks to "resize images", prepare images for web, social, slides, or print, or batch-convert a folder of photos. Asks for the source folder, outputs resized copies into subfolders.

- - Write

- # /resize-images — Image Resizer for Web, Social, and Print

- List all image files in the folder (non-recursive). Supported formats: `.jpg`, `.jpeg`, `.png`, `.tif`, `.tiff`, `.webp`.

-

- ```python

- import os, sys

-

- folder = sys.argv[1]

- exts = {'.jpg', '.jpeg', '.png', '.tif', '.tiff', '.webp'}

- images = [f for f in os.listdir(folder) if os.path.splitext(f.lower())[1] in exts]

- images.sort()

- for img in images:

- print(img)

- ```

-

- Report the count: `"Found N image(s) in [folder]. Ready to resize."`

- Run this to confirm Pillow is available:

- ## Step 4: Create output folders

-

- Inside the source folder, create one subfolder per requested mode:

-

- - `resized-web/` — if web sizes were requested

- - `resized-social/` — if social sizes were requested

- - `resized-slides/` — if slides sizes were requested

- - `resized-print/` — if print sizes were requested

-

- ```python

- import os, sys

- folder = sys.argv[1]

- modes = sys.argv[2:] # 'web', 'social', 'slides', and/or 'print'

- for mode in modes:

- os.makedirs(os.path.join(folder, f"resized-{mode}"), exist_ok=True)

- ```

-

- ## Step 5: Resize images

-

- Run this Python script via Bash, passing the folder path and modes as arguments:

-

- ```python

- import sys

- import os

- from PIL import Image

-

- folder = sys.argv[1]

- modes = sys.argv[2:] # 'web', 'social', and/or 'print'

-

- exts = {'.jpg', '.jpeg', '.png', '.tif', '.tiff', '.webp'}

- images = [f for f in os.listdir(folder) if os.path.splitext(f.lower())[1] in exts]
