Frequently Asked Questions
What is a BlurHash?
A BlurHash is a very short string that represents a blurred, low-detail version of an image. Apps store the hash alongside an image and render the blur as a placeholder while the real image downloads, avoiding empty gray boxes.
How do I use a BlurHash on my website?
Generate the hash here and store it with your image data. On the page, decode the hash to a small blurred canvas and show it until the full image finishes loading, then swap it in. It dramatically improves perceived load speed.
Can I adjust how detailed the blur is?
Yes. The component counts control how much horizontal and vertical detail the hash captures — more components mean a richer blur but a slightly longer string. A contrast control fine-tunes the punch of the preview.
Can this tool decode an existing BlurHash?
Yes. Paste a BlurHash string and the tool renders its blurred preview, so you can verify a hash or recover the placeholder image. Everything runs in your browser with nothing uploaded.
