Show HN: AvifHash v0 – Compact and efficient image placeholders (juliobbv.com)

AvifHash leverages the power of AVIF to create image placeholders that are both compact and efficient.

This Proof of Concept shows promising results: at 27 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 very small: the entire demo page (including parsing and re-hydration code) is only 2.3 kB gzipped.
