WebP is Google's open raster format built on the VP8 video codec (lossy) and its VP8L extension (lossless). On osm2cdr.ru the map is rendered to PNG and then transcoded to WebP via Pillow. In lossy mode the file is 25–35% lighter than JPEG; in lossless mode 26% lighter than PNG. WebP supports transparency and works in every mainstream browser. It is a finished map image, not editable layers — a handy lightweight format for previews and thumbnails, but not a replacement for GeoTIFF in full-size cartographic export.
