A tiny dependency-free JavaScript library (2.5kb gzipped) for truly lazy loading responsive images, background images, and HTML. It is SEO friendly, supports WebP and AVIF formats, and avoids unnecessary network requests.
Use cases
- lazy load responsive images on a website
- defer loading images below the fold to improve page speed
- serve webp or avif images with fallbacks
- lazy load background images
- lazy load HTML fragments containing JavaScript
- improve SEO while lazy loading images
When to choose
- you need a lightweight, dependency-free lazy loading solution
- SEO matters and you want valid HTML with a real src fallback
- you want to serve modern image formats like WebP and AVIF with fallbacks
- you need to lazy load HTML or background images, not just img tags
When to avoid
- you prefer native loading="lazy" and browser-level srcset support
- you need a framework-specific solution (React/Vue components)
- you require IntersectionObserver-based APIs with fine-grained callbacks
