Layzr.js is a small JavaScript library for lazy loading images on web pages. It defers image loading until elements scroll into view and selects the best source via srcset support or devicePixelRatio-based retina fallbacks.
Use cases
- lazy load images as the user scrolls
- defer offscreen image loading to speed up page load
- serve retina images only on high-dpi screens
- use srcset with a fallback for older browsers
- reduce initial bandwidth on image-heavy pages
When to choose
- you need a tiny, dependency-free vanilla JS lazy loader
- you must support browsers without native srcset via retina fallbacks
- you want configurable data attributes and scroll events
When to avoid
- your target browsers support native loading='lazy'
- you need an actively maintained library with recent fixes
- you use a framework with built-in lazy loading (e.g., next/image)
