Keep small icons simple
A clear silhouette and strong contrast help a logo remain recognizable at 16 pixels. Inspect the smallest previews before publishing. A square source of at least 512 pixels gives the largest export more detail.
Choose the right framing
Contain preserves the whole image. Crop fills the square and trims the edges. Padding leaves space around the artwork; the background color also fills transparent areas in the original image.
Publish the icon set
Extract the bundle into your website public root. Add the supplied link elements to the page head, merging with existing icon declarations. The manifest references the included 192 and 512 pixel Android images. Set the manifest name and short_name to your site name before publishing. Browser icon caches can take time to refresh.
