bLazy is a lightweight pure JavaScript library (under 1.4KB gzipped) for lazy loading and multi-serving images, iframes, videos, and other src-based elements. It supports srcset, the picture element, retina serving, and background images without any third-party dependencies.
Use cases
- lazy load images as the user scrolls
- serve responsive images with srcset and picture element
- serve retina images on high-dpi devices
- lazy load iframes and HTML5 videos
- reduce bandwidth and speed up page load
- lazy load background images
When to choose
- you need a tiny dependency-free lazy loader for legacy browsers including IE7+
- you want multi-serving of responsive/retina images in an older codebase without native loading=lazy support
When to avoid
- you target only modern browsers - native loading="lazy" and IntersectionObserver cover most needs
- you need an actively maintained library - the last release was in 2019 and the demo site is down
