Convert to AVIF

AVIF applies AV1 intra-frame compression to still images and currently offers the highest compression efficiency of any image format: about 20% smaller than WebP and 50% smaller than JPG at equal subjective quality, with 10/12-bit color depth, HDR and alpha support. All major browsers decode it natively.

This group converts eight source formats: HEIC decodes via heic-convert, SVG rasterizes at 2x density, and other bitmaps re-encode with Sharp. Quality is adjustable from 1 to 100 (default 80). Longer encode times are an inherent trait of the AV1 algorithm. Ideal for hero images and archives where every kilobyte matters.
