Faster websites start with smaller images
Images are usually the heaviest part of a page. The optimize tools combine right-sizing and modern-format conversion to cut page weight, the direct path to better Core Web Vitals and rankings.
Right-sizing matters more than most sliders: serving a 4000px photo into an 800px slot wastes bytes no quality setting can recover. The optimizers cap width at what your layout actually displays, then re-encode to WebP or AVIF, both levers in one pass, entirely in your browser.
Frequently asked questions
What does an optimizer do that a compressor does not?
Compression adjusts quality and format. Optimization also right-sizes the image: anything wider than your chosen maximum is scaled down proportionally first. Pixel count drives file size more than anything else, so right-sizing plus compression beats compression alone.
How much smaller will my images get?
It depends on how oversized they were to start. A 4000px phone photo capped at 1280px and encoded as WebP typically lands 80–95% smaller. The exact before/after numbers are shown per file before you download.
