Frequently Asked Questions

What is BlurHash?

BlurHash is an algorithm that encodes an image placeholder into a short string. It's widely used in modern web and mobile apps to provide a colorful blur while the actual image loads.

How do I use the generated string?

You store the string in your database alongside the image URL. On your frontend, you use a BlurHash decoder library to render the string onto a canvas before the real image arrives.

Is this tool free and private?

Yes. Like all our batch tools, it runs entirely in your browser. Your images are never uploaded to any server, ensuring total privacy and maximum security.
