SVGZ - Compressed SVG File
This is a Scalable Vector Graphics file (SVG) that has been compressed with the GZIP compression algorithm. It contains graphics data described in XML format and supports graphics elements such as transparency, gradients, filters and animations. SVGZ files usually take 50 to 80 percent less storage space than standard uncompressed SVG files. The Adobe SVG Viewer will automatically decompress SVGZ files when opened.
