How i can perform image optimisation?

Audit your assets: compress ruthlessly with tools like JPEGmini to trim file sizes sans visible artifacts, aiming for under 100KB per image. Embrace WebP or AVIF for superior compression ratios that load like butter.
Craft alt tags that double as accessibility wins and SEO boosters, weaving in long-tail keywords naturally. Lazy loading keeps the scroll smooth by deferring non-critical loads, while srcset ensures responsive images scale flawlessly across viewports.

The best ways to optimize images are to compress the files, use the right format (JPEG, PNG, WebP), add descriptive alt text, resize the images for web, and use lazy loading to speed up your site.
