Image Quality Checker

概要

This open-source Python tool streamlines the process of auditing image assets before they are published. It goes beyond simple file extensions, sniffing the real file format using magic bytes, verifying resolution, estimating JPEG compression quality from quantization tables, and detecting extension mismatches. Designed for efficiency, it can process images in batches and export comprehensive reports in human-readable text, JSON, or CSV formats, making it ideal for both manual checks and automated workflows, including integration with AI agents.
