Handsum: An LQIP Image File Format

Quality: 8/10 Relevance: 9/10

Summary

Handsum introduces a fixed-size, DCT-based LQIP thumbnail format and compares it with Thumbhash, Blurhash, WebP, and ETC2. The article explains Handsum's stages (resize, YCbCr, chroma subsampling, DCT, quantization, loop filter) and discusses fixed output sizes (48–147 bytes) across q settings, plus potential use cases like embedded catalogs.
