What is JPEG XL?
JPEG XL (.jxl) is a next-generation image format standardised in 2022. It is designed to replace both JPEG and PNG as the universal image format for the web and professional workflows.
Compared to traditional JPEG, JPEG XL achieves up to 60% smaller file sizes at the same perceived quality. Compared to PNG, it offers significantly better lossless compression — making it ideal for compressing images without sacrificing detail.
JPEG XL supports lossless and lossy compression, HDR, wide colour gamut, transparency, animation, and progressive decoding — the most versatile image format available today.
Why compress images?
Large image files slow down websites, consume storage, and increase bandwidth costs. Compressing images is one of the highest-impact optimisations you can make — it directly improves page load speed, Core Web Vitals scores, and user experience.
For designers, developers, and content teams, converting assets to JPEG XL before publishing means faster sites, lower CDN costs, and better SEO rankings — all without touching image quality.
