Serve the right pixels in an efficient format, reserve width and height to prevent shifts, prioritize the likely LCP image, and lazy-load only images below the first view.

Compress images without the guesswork
Smaller files, your size target, no nonsense. Drop in JPG, PNG, WebP, AVIF, HEIC, TIFF, GIF, or SVG files.

Start with the rendered dimensions
A compressed 4000-pixel image is still wasteful in a 700-pixel slot. Generate responsive candidates and let the browser select one using srcset and sizes. Keep a practical fallback for the audience you support.
Protect layout and loading priority
Width and height attributes reserve aspect-ratio space before bytes arrive. The likely hero or LCP image should be discoverable in initial HTML and must not be lazy-loaded, while images farther down the page can wait.
Measure the page, not just the file
Lab tools expose opportunities, while field data shows real devices and networks. Review LCP, interaction responsiveness, layout shifts, caching, server latency, and visual quality together.
