Quick Start (2 min)View Source How it Works

Built for Speed

Optimize the critical render path by minimizing DOM reflows, deferring off-screen images, and providing a consistent user experience.

Serious UX Wins

Users enjoy fast, stable pageloads with instant Blurhash previews, eliminating Cumulative Layout Shift (CLS) from images (even on slow networks).

Lightweight Loading

Lazy-loading offscreen images reduces initial pageload size and allows your page to become ready faster — boosting Interaction to Next Paint (INP).

Superior Search Performance

Google emphasizes Core Web Vitals as a major ranking signal. Optimizing these metrics can improve your website's performance in search engine results.

"We highly recommend site owners achieve good Core Web Vitals for success with Search"

Developer Friendly

The easiest way to get started with Blurhash.

No backend changes or migrations needed. Swap your existing image URLs with Blurhash URLs.

Framework-tested (Remix, Astro, Next, Vite) with support for client and server-side rendering (SSR, SSG).

Open source, written in Typescript.

How it Works

Visionary Image renders three layers to provide the fastest possible placeholder rendering, improving Core Web Vitals like Cumulative Layout Shift (CLS). Blurhash URLs embed placeholder data directly in the image URL.

IMAGE LAYERS:

01. A base layer with the image's aspect ratio is quickly rendered in the DOM

02. A soft, configurable blur is overlaid on a canvas

03. The full image loads, replacing the blur layer
