What image formats does this skill support?

The Image Cropper skill supports any format compatible with the Pillow library, including PNG, JPEG, and WebP, with specific handling for transparency in PNG files.

How does it handle backgrounds that aren't a perfectly solid color?

The skill includes a '--fuzz' parameter that sets color tolerance. Increasing the fuzz value allows the tool to identify and trim pixels that are nearly identical to the background color.

Does this skill require any external Python packages?

Yes, you must have the Pillow library installed. You can set it up by running 'pip install Pillow' in your terminal.

Can I keep a small margin around the object after cropping?

Absolutely. You can use the '--padding' argument to specify the number of pixels to keep around the content to prevent the crop from being too tight.

Design Tools

Automatically trims blank borders and transparent space from images to isolate core content using intelligent detection.

Image Cropper is a specialized Claude Code skill designed to automate the tedious task of trimming unused space from visual assets. It leverages the Python Pillow library to intelligently detect background colors—whether transparent, white, or a specific hex value—and crops the image to its tightest bounding box. This tool is ideal for developers and designers preparing UI assets, cleaning up screenshots, or standardizing image sizes for web applications, offering granular control over padding and color tolerance to ensure high-precision results.
