AI Analysis

●●SolidNiche GemBig Brain

Fixed-size LQIP format for database columns when Thumbhash already does smaller.

Strengths
  • Fixed 48-147 byte sizes enable fixed-width database columns for faster iteration
  • Simpler than JPEG spec (186 pages) — educational value for understanding DCT
  • Working C decoder compiled to Wasm with real benchmark comparisons included
Weaknesses
  • Thumbhash achieves 24-27 bytes — Handsum is 2-5x larger for similar quality
  • Another LQIP format in a space already served by Blurhash and Thumbhash
Target Audience

Web developers optimizing page load times, database engineers storing thumbnails
