What is a Blur Data Placeholder?
When lazily loading high-resolution images, showing a blank space or a generic spinner can feel jarring to users. Modern frameworks like Next.js offer a feature to show a heavily blurred, extremely low-resolution version of the image while the full version loads.
How it works
This tool takes your high-resolution image, scales it down to just a few pixels wide (e.g., 10x10), and compresses it as a highly optimized JPEG Base64 string.
The resulting string is usually less than 500 bytes and can be safely embedded directly into your HTML document or React components. When the browser renders it, CSS filters (like backdrop-filter or blur()) are applied to stretch the tiny image out smoothly.
