When someone adds your website to their iPhone or iPad home screen, iOS uses the Apple Touch Icon as the app-like icon. Without one, iOS takes an ugly screenshot of your page instead. Here's everything you need to know.

What is an Apple Touch Icon?

An Apple Touch Icon is a special PNG image that iOS devices use when a user bookmarks your site to their home screen. It works like a native app icon — iOS automatically applies its signature rounded corners and gloss effect (on older iOS versions).

It's declared in HTML with:

<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

Required Size: 180×180 Pixels

In 2026, you only need one size: 180×180 pixels. Here's why:

Since iOS can scale down but cannot scale up well, providing the largest size (180×180) is the safest approach. One file covers all devices.

Historical note: In the past, you needed separate sizes for each device (57, 60, 72, 76, 114, 120, 144, 152, 167, 180). Modern iOS handles scaling well enough that 180×180 alone works perfectly.

File Format Requirements

HTML Implementation

Basic (one line)

<link rel="apple-touch-icon" href="/apple-touch-icon.png">

With explicit size

<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">

Automatic discovery (no HTML needed)

If you place a file named apple-touch-icon.png in your website's root directory, iOS will find it automatically — even without any HTML declaration. However, explicitly declaring it in HTML is still recommended for reliability.

Since iOS 7+ no longer adds the gloss effect, apple-touch-icon and apple-touch-icon-precomposed behave identically. Just use apple-touch-icon.

Design Tips

Common Mistakes

  1. Using transparency → Black background on iOS home screen
  2. Adding rounded corners manually → Double rounding effect
  3. Wrong file format → SVG is not supported; use PNG
  4. Too small → Providing 57×57 looks blurry on modern Retina screens
  5. Forgetting to test → Always test by actually adding to home screen on a real iPhone
