SVGZ — Compressed SVG (gzip)
付款前显示价格SVGZ is plain SVG compressed with gzip. SVG is text-based XML by nature and compresses extremely well: a multi-megabyte district map becomes a file 60-80% smaller — with no quality loss, since gzip is lossless. Our exporter does this in one step: the map is honestly rendered through QGIS into a full styled SVG, then compressed with gzip level 9. All modern browsers unpack .svgz on the fly, and Inkscape and Illustrator open it directly. Inside is the same object-name catalogue layer as in plain SVG: names are searchable in the editor's object list, and no extra labels are drawn on the map.

主要特点
关于 SVGZ 格式
SVGZ is not a separate format but the same SVG, packed with gzip. The extension serves as a hint to the browser and to editors that the content is compressed. A vector map is text with thousands of repeating fragments, which is why it compresses particularly well.
It makes sense wherever somebody downloads the file: a map on a page, an archive of layouts, serving from static hosting. The saving runs end to end — less disk space, less traffic, faster loading, and the image does not lose a single dot.
What you get: a full styled map, rendered by the same pipeline as the ordinary SVG and compressed with gzip at maximum level. There is no need to unpack it by hand — browsers, Inkscape and Illustrator read the file directly; if you do end up needing the source, gunzip gives back the ordinary SVG.

谁在使用 SVGZ 地图
如何导出 SVGZ
导出后如何打开
- A browser — open the file with a double click: Chrome, Firefox, Safari and Edge unpack it themselves.
- Inkscape — opens and saves compressed SVG directly, no separate unpacking step needed.
- The command line — gunzip gives back an ordinary .svg if a program does not understand the compressed variant.
- Serving from a server — set the image/svg+xml content type and the gzip encoding headers, otherwise the browser will show a meaningless set of characters instead of the map.
- A check after deployment — open the file's address in a browser: if the map rendered, the headers are set correctly.
