Installation

  1. Install the NuGet package as described in the Installation Guide .
  2. Configure licensing with the Metered Licensing instructions to unlock full functionality.

Example: Compressing a PNG Image 

using (var image = Image.Load("sample.png"))
{
    image.Save("compressed.png", new PngOptions
    {
        CompressionLevel = 9,
        Progressive = true,
        ColorType = PngColorType.IndexedColor,
        Palette = ColorPaletteHelper.GetCloseImagePalette((RasterImage)image, 1 << 5)
    });
}

For WebP compression, you can fine-tune parameters with WebpOptions , setting lossless to false and defining a quality percentage.
