Web App / Progressive Web App

An Icon is shown on the device home screen when saving a bookmark. This is similar in nature to the "favicon" for websites. The "-precomposed" portion of the filename prevents Apple from automatically adding gloss, rounded corners and drop shadows.

Refer to the "Webpage Icon" Apple documentation page for additional details.

Apple invented the iOS Web Clip idea, but it has been picked up by Chrome (and others).

We've also included a manifest.json file for you as a starting point for your Progressive Web App.

See the "index.html" source code for how to include the icons in your page(s).

Universal Windows Platform (UWP)

The following information was derived from:

Splash Screen sizes derived from:

Based on the description provided here, the system selects appropriate images based on the following scheme:


Where <name> can be anything you want. According to the guide, they're recommending using a naming convention of "AppNameSmallTile.scale-XXX.png". I found this to be rather confusing, so I decided to just stick with naming the images according to the attribute definition, which I believe is less confusing.

When referencing an image in your code, just use NAME.EXT. The ".scale-XXX" portion of the file name is not included in the code. The system automatically selects the appropriate image/scale as needed. Icon Slayer uses a naming convention that matches the element attribute, I believe this is least confusing.

Usage + Known Issues

- You can load PNG, JPG or BMP images. PNG files can have transparency.

- Flatten source PNGs. Some browsers require source PNG files to be "flattened", meaning that PNG files should not have "layer" information in them. The PNG can have an alpha channel (where parts of the image is invisible), but "layer" information can be problematic for some browsers. Flattening maintains transparency, but just reduces all layers to a single layer.

- Reduce image dimensions. Source PNGs should be no larger than 1240 x 1240 pixels. The smaller your source file, the faster things will process. A good rule of thumb is to make your source file as big as the biggest icon you need.

- Safari on Mac can freeze during export. Icon Slayer uses Adobe Flash, and this is a known problem that Adobe has not resolved. Try using another browser such as Mozilla Firefox or Google Chrome.
