Opticross helps developers analyze responsive images and identify image optimization opportunities on websites, available both as a Chrome extension and a CLI tool.
What It Does
- Measures image rendering dimensions
- Analyzes responsive image behavior
- Generates optimization recommendations
- Calculates estimated bandwidth savings
- Identifies potential image delivery issues
How It Works
All image analysis is performed locally — either in your browser via the extension or on your machine via the CLI. No page content or analysis results are transmitted to external servers.
