How this service works

What a page shows while an image loads: its BlurHash, a tiny blurred WebP preview as a data URL, its average color and its dimensions.

Output

Returns a JSON object with: width and height (integer pixel dimensions), blurhash (a compact BlurHash string for rendering a blurred placeholder), average_color (hex string e.g. '#7a6b55'), and preview_data_url (a base64-encoded tiny blurred WebP image as a data URL, ready to embed in HTML or CSS).

Example use cases

Lazy-load placeholder for blog images

“I have a blog post with images and I want smooth lazy loading — can you fetch the BlurHash, average color, tiny WebP preview, and dimensions for https://myblog.com/images/hero.jpg so I can show a blurred placeholder while the full image loads?”

E-commerce product image skeleton

“Before our product photos load on the shop page, I want to show a colored skeleton that matches the actual image. Can you get the average color, BlurHash, preview data URL, and pixel dimensions for https://shop.example.com/products/shirt-blue.png?”

CMS image metadata enrichment pipeline

“I'm uploading images to our CMS and need to store placeholder metadata for each one. Can you extract the BlurHash, average hex color, blurred WebP preview data URL, and width/height for this image: https://cdn.mycms.io/uploads/landscape.webp?”

When to prefer

Choose this endpoint when you need all the ingredients for a high-quality image lazy-loading experience in one call: BlurHash for CSS/canvas rendering, a tiny inline WebP preview for LQIP (Low Quality Image Placeholder) techniques, the average color for background/skeleton theming, and exact dimensions for layout reservation. It is ideal for front-end pipelines, CMS enrichment, and any scenario where you want to avoid layout shift and improve perceived load performance without running your own image analysis server.
