WebP (.webp)

Background

    ▪ Registered MIME type: image/webp
    ▪ WebP raster image format.
    ▪ Binary format.
    ▪ Stores a single image.
    ▪ Stores color bitmaps at a resolution of 8 bits per channel.
    ▪ Supports alpha channels.
    ▪ Introduced in 2010 by Google to provide both lossy and lossless compression of images on the web.

Import and Export

  • Import["file.webp"] imports a WebP file as an image.
  • Import["file.webp",elem] imports the specified element from a WebP file.
  • The import format can be specified with Import["file","WebP"] or Import["file",{"WebP",elem,…}].
  • Export["file.webp",expr] exports an image, graphics, or any other expression as a raster image to WebP.
  • When exporting Wolfram Language graphics or arbitrary expressions to WebP, the resulting image has the same raster size as its displayed form.
  • Image objects are by default exported at their raster size.
  • Because WebP is a raster image format, all fonts are rasterized on export.
  • See the reference pages for full general information on Import and Export.
  • ImportString and ExportString support the WebP format.
