Show HN: AvifHash v0 – Compact and efficient image placeholders (opens in new tab)

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.
