Image compression is the process of reducing an image file’s size while maintaining acceptable visual quality, typically through modern formats like WebP or AVIF and appropriate resizing for how the image will actually be displayed.
Since images are often the largest individual assets on a webpage, proper compression is one of the most impactful, straightforward ways to improve page speed and Core Web Vitals metrics like Largest Contentful Paint.
A common mistake is uploading full-resolution, uncompressed images directly from a camera or design tool without any optimization, unnecessarily bloating page weight and slowing down load times for every visitor.
