Image Size Checker - Oversized Image Finder is a Chrome extension designed to enhance website performance by identifying oversized images that negatively impact page speed. With a single click, users can scan all images on a webpage and see a comparison of natural versus displayed dimensions, highlighted with color-coded badges directly on the images. This tool is particularly beneficial for web developers and site owners looking to optimize their websites for better loading times.

Key features include visual indicators for oversized images, estimated bandwidth savings, and a summary of potential page weight reduction. The extension is aware of device pixel ratios, ensuring accurate assessments for Retina displays. Users can view results in a popup or toggle on-page overlays, making it easy to identify and address image optimization issues. Importantly, the extension operates locally without data collection, ensuring user privacy.
