WebP — Google Web Image Format

Open Beta

.webp · image/webp

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.

WebP فارمیٹ کے بارے میں

WebP is Google's raster format, grown out of the VP8 video codec. It works in two modes: lossy, when weight matters, and lossless, when pixel accuracy matters. Transparency is supported by both modes, and WebP is displayed by every current browser.

For maps this is a screen format: a preview in a catalog, a picture in an article, an asset in a mobile app. Where PNG weighs more than it should and JPEG blurs thin road lines and labels, WebP gives a reasonable compromise between weight and readability.

The map is rendered to PNG and then re-encoded into WebP: lossy mode and quality 80 by default, or lossless mode with exact pixel reproduction if you prefer. This is a finished image: layers are not editable and there are no coordinates inside. For a print house take TIFF or PDF, for a GIS — GeoTIFF.

WebP نقشے کون استعمال کرتا ہے

🏗

Map previews and thumbnails on web pages to save bandwidth

A map preview in a catalog or a feed: the page loads noticeably faster than with PNG.

💻

Responsive images via the <picture> tag with JPEG/PNG fallback

Responsive layout through the picture tag — modern browsers take WebP, the rest get the fallback PNG.

📊

Map assets in mobile apps to reduce bundle size

Map assets in a mobile application: the build gets lighter with no loss of readability.

🎨

Lossless WebP for tiles with transparency and flat-colour areas

Lossless mode for pictures with transparency and large areas of flat color.

ایکسپورٹ کے بعد کیسے کھولیں

A browser — just open the file: Chrome, Firefox, Edge and Safari 14 and newer display WebP without plugins.
A web page — <picture><source srcset="map.webp" type="image/webp"><img src="map.png" alt="map"></picture>: older clients will get the fallback PNG.
GIMP, Affinity Photo, Photoshop 2022 and newer — they open and save WebP; handy for cropping the picture or adding a caption.
ImageMagick or cwebp — re-encode to your own requirements: magick map.webp -quality 70 out.webp, or cwebp -lossless for exact pixel reproduction.
Not for print — this is an RGB picture for the screen; for a print house take TIFF, CMYK TIFF or PDF.
