"Image Size Checker" is a browser extension developed by Daniel Amenou that aims to assist web developers and designers in optimizing the use of images on their web pages. This free Chrome extension provides valuable tools to ensure that images are of the optimal size and aspect ratio.

One of the key features of "Image Size Checker" is its ability to provide size recommendations for images based on their file type and dimensions. The extension alerts users if an image exceeds the recommended file size, allowing them to make necessary adjustments for better performance.

Additionally, the extension includes an aspect ratio checker, which detects any mismatch between the rendered aspect ratio of an image and its intrinsic aspect ratio. This feature ensures that images display as intended, preventing any distortion or stretching.

To provide immediate feedback, "Image Size Checker" offers in-page warnings. Problematic images are bordered in red, accompanied by detailed warning messages. This makes it easy for developers and designers to identify and address any issues promptly.

Furthermore, the extension provides quick image information when hovering over an image. Users can see the file size of an image without the need to dig into developer tools, allowing for quick assessments and optimization.

By harnessing the power of "Image Size Checker," web developers and designers can optimize the images on their sites, improve loading times, and enhance the overall user experience. This browser extension is a valuable tool for anyone looking to ensure their web images are of the highest quality and performance.
