Compact Size
BlurHash encodes images into a very small string representation, which typically consists of only 20-30 characters. This compactness makes it bandwidth-efficient, suitable for scenarios where data transfer sizes need to be minimized, like in thumbnails or during initial loading phases.
Fast Decoding
The decoding process of BlurHash is relatively fast and can be performed directly in the browser or on a device without the need for heavy computational resources, making it well-suited for dynamic web applications and mobile apps.
Privacy-Friendly
BlurHash provides a way to visually represent an image without transmitting the actual image data. This can be useful for maintaining privacy and confidentiality while still offering a visual placeholder for the content.
Visual Placeholder
By rendering a blurry placeholder, BlurHash improves user experience during image loading by providing an immediate visual cue, reducing the impression of loading times.

AvifHash leverages the power of AVIF to create image placeholders that are both compact and efficient. This Proof of Concept shows promising results: at 28 characters, AvifHash outperforms BlurHash https://blurha.sh/ (using 4x3 components) in quality and detail retention. At a similar quality, BlurHash needs 54 (5x5) to 76 characters (6x6 components). Given that AVIF decoding is done by the web engine, AvifHash is... - Source: Hacker News / almost 2 years ago

Very nice! I see that when you're scrolling, a highly-pixelated version of the picture is displayed before the actual picture is shown. Wouldn't it be better to use something like https://blurha.sh? I used it on a recent project and it works really work for this kind of use cases. Source: almost 4 years ago

Maybe it was [blurhash](https://blurha.sh/)? - Source: Hacker News / almost 4 years ago
I came across blurha.sh a while ago that does this very nicely. Basically you generate a pretty short string from an image that can be used to display a blurred version of the image while the image itself is still being downloaded. Generating that string can be done on the device, but I figure it would be much better for you to do it on the backend since your image will be uploaded there anyway. Source: almost 4 years ago
