Selecting a custom icon image
You can use any image file format (JPG, PNG, GIF) to create custom icons. You can either drag-and-drop the image files onto the Home screen or select them from the Photos app.
Adding text to the icon
If you want to add text to your icon, simply tap the icon once to bring up the editing tools. Tap the Text tool at the bottom left corner of the screen to enter edit mode. Type the text you want to appear in the icon and then tap Done.
Resizing the icon
To resize the icon, tap and hold the icon until four dots appear around its edges. Drag the corners inward or outward to change the size of the icon.
Rotating the icon
Tap and hold the icon until two dots appear around its edge. Then rotate the icon clockwise or counterclockwise to change the orientation of the icon.
Saving the icon
When you’re done customizing your icon, tap Save. Your changes will be saved to the Photo Library.
