- LQIPs are small images that load quickly, providing immediate visual feedback while full-resolution images load.
- Handsum is a new LQIP file format based on Discrete Cosine Transform (DCT) like Blurhash, Thumbhash, and JPEG.
- Handsum files have fixed sizes: 48 bytes at lowest quality and 147 bytes at highest, enabling fixed-size database columns.
- The format uses YCbCr color space with 4:2:0 chroma subsampling to reduce file size by prioritizing luma over chroma.
