AVIF — AV1 Image File Format
Open Beta.avif · image/avif
AVIF is a modern raster format built on a key frame of the AV1 video codec inside a HEIF container. On osm2cdr.ru the map is first rendered to PNG and then transcoded to AVIF via Pillow. At comparable visual quality the file is 30–50% lighter than WebP, which noticeably saves bandwidth for mobile users. It is a flat picture of the map, not editable layers: labels and outlines are baked into pixels. Note that the alpha channel is dropped during conversion, so the background becomes opaque.
