What it does

Official website for the FLIF image format

FLIF development has stopped since FLIF is superseded by FUIF and then again by JPEG XL , which is based on a combination of Pik and FUIF . For more information, see Jon's JXL info page or visit the JPEG XL Discord server . FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG, lossless JPEG2000, and lossless JPEG XR in terms of compression ratio. Even if the best image format was picked out of PNG, JPEG 2000, WebP or BPG for a given image corpus, depending on the type of images (photograph, line art, 8 bit or higher bit depth, etc), then FLIF still beats that by 12% on a median corpus (or 19% on average, including 16-bit images which are not supported by…from flif.info

    AvifHash v0 – Compact and efficient image placeholders2024 · juliobbv.com · ▲8

    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.
