@unpic/svelte

Svelte component for responsive, high-performance images. Generates a responsive <img> tag that follows best practices, with the correct srcset, sizes and styles. Detects image URLs from most image CDNs and CMSs and can resize images with no build step.

Features

• Just an <img> tag! No extra elements, no runtime JavaScript. Easy to style.
• Automatically generates correct srcset and sizes attributes for responsive images
• Handles responsive resizing of images, preserving aspect ratio
• Uses native lazy loading and async decoding for offscreen images
• Handles different image layouts: fixed, constrained and full width
• Uses eager loading and high priority fetching for important images
• Delivers modern image formats, including WebP and AVIF if supported by your browser
• No built step or server-side rendering required: uses your existing image CDN or CMS, with no additional configuration
• Uses unpic to support most image CDNs, including Cloudinary, Imgix, and Shopify
• Can generate a low-res background image for a blurred placeholder effect
