Best Compress Images WordPress Plugins

Image compression plugins for WordPress reduce file sizes of JPEG, PNG, GIF, and WebP uploads through lossy or lossless optimisation, stripping unnecessary metadata and applying compression algorithms that maintain acceptable visual quality while shrinking transfer size. Unoptimised images are among the most common causes of poor Google PageSpeed Insights and Core Web Vitals scores, making image compression one of the highest-ROI performance improvements available to WordPress site owners. The best compression plugins process images automatically on upload, offer bulk optimisation for existing libraries, and use cloud-based APIs — Imagify, ShortPixel, Smush, Kraken — to offload the CPU-intensive compression work from the hosting server. Sites targeting fast mobile load times, high Lighthouse scores, or lean hosting bandwidth consumption should treat automatic image compression as a standard workflow step.
