Favicon vs App Icon

Differences, use cases, and when to use each

Last updated: April 6, 2026

Favicons are small browser tab icons (16x16 to 32x32). App icons are the larger icons shown on device home screens and app stores (up to 1024x1024). Modern workflows generate both from a single high-resolution source image.

When to Use Each

When to Use Favicon

Focus on favicon design for any website. Favicons appear in tabs, bookmarks, and browser history — a clear, recognizable 16px icon reinforces your brand.

When to Use App Icon

Focus on app icons when building Progressive Web Apps (PWAs), native mobile apps, or any app that will be installed on a device home screen.

Pros & Cons

Favicon

Universal web requirement
Consistent browser display
Simple format
Must be legible at 16px (very limited detail)
Many size variants needed

App Icon

Full brand expression at large sizes
Required for installable PWAs
App store presence
Multiple sizes and formats required per platform
Complex asset generation

Verdict

Generate both from the same high-resolution source. Most favicon generators produce all needed sizes. Design your icon to work at both 16px (simplified) and 512px (detailed).

Key Takeaways: Favicon vs App Icon

Choosing between Favicon and App Icon depends on your specific requirements, not on which format is “better” in absolute terms. Both exist because they solve different problems well. In professional projects, you will often use both — the key is understanding which context calls for which tool.

If you are starting a new project and have flexibility in choosing your data format or tool, consider your team's familiarity, your ecosystem requirements, and the long-term maintenance implications. The comparison table and pros/cons above should help you make an informed decision for your specific situation.

Frequently Asked Questions

What size should my source icon be for favicons?
Start with at least 512x512 pixels, ideally 1024x1024. Favicon generators downsample to all required sizes. SVG is best as a source since it scales perfectly to any size.
Can I use an SVG as a favicon instead of ICO or PNG?
Yes. Modern browsers support SVG favicons via <link rel='icon' type='image/svg+xml' href='icon.svg'>. SVG favicons scale perfectly and can even respond to dark mode using CSS media queries inside the SVG. Include an ICO or PNG fallback for older browsers.
What sizes do I need for Apple Touch Icons versus Android icons?
Apple requires a 180x180 PNG touch icon (apple-touch-icon). Android PWA icons need 192x192 and 512x512 PNG icons specified in the web manifest. Android also supports maskable icons with safe zone padding. Generate all sizes from a single 1024x1024 source using a favicon generator tool.
How do I make my favicon look good in both light and dark browser themes?
SVG favicons can include a CSS media query for prefers-color-scheme: dark, automatically switching colors. For PNG/ICO favicons, choose a design that works on both light and dark backgrounds — typically by adding a subtle border or using colors with sufficient contrast against both themes.
What is a maskable icon and when do I need one?
Maskable icons include extra padding so Android can crop them into different shapes (circle, rounded square, squircle) depending on the device. Without masking, Android adds a white background behind your icon. Specify 'purpose': 'maskable' in your web manifest for icons designed with safe zone padding.
How does the web app manifest connect to app icons for PWAs?
The manifest.json (or manifest.webmanifest) file lists all app icon sizes and their purposes. It also defines the app name, theme color, and display mode. When a user 'installs' your PWA, the browser reads this manifest to create the home screen shortcut with the correct icon and splash screen.
