Generating Modern Web & Mobile Favicons

Favicons (favorite icons) are visual branding elements displayed in browser tabs, bookmarks, mobile home screen shortcuts, and search engine results pages. Modern web apps require multiple icon resolutions to render cleanly across high-DPI Retina displays, iOS Safari home screens, and Android Progressive Web Apps (PWAs).

Multi-Resolution Package Standards

  • favicon.ico: Multi-resolution legacy icon containing 16x16, 32x32, and 48x48 pixel buffers for internet explorer and traditional desktop browsers.
  • favicon-32x32.png: Standard resolution for modern desktop browser tabs (Chrome, Firefox, Edge, Safari).
  • apple-touch-icon.png (180x180): High-resolution icon used when users bookmark your website to an iOS home screen.
  • android-chrome-512x512.png: High-resolution icon for Android PWA splash screens and web app manifests.

100% In-Browser Privacy

All canvas scaling, icon generation, and ZIP packaging occur locally inside your browser memory. Your files are processed on your device and are never uploaded.

Frequently Asked Questions

What favicon sizes are generated in the ZIP package?

Our favicon generator creates 16x16 px (classic browser tab), 32x32 px (retina browser tab), 48x48 px (desktop shortcut), 180x180 px (Apple Touch Icon), 512x512 px (PWA manifest icon), plus a multi-resolution favicon.ico file.

Are my logo files uploaded to any server?

No. All canvas rendering, icon scaling, and ZIP package creation occur 100% in local browser memory. Your files are processed on your device and are never uploaded.

How do I embed these favicons in my HTML website?

Add <link rel="icon" href="/favicon-32x32.png"> and <link rel="apple-touch-icon" href="/apple-touch-icon.png"> tags to your website's <head> section.

What input image formats work best for generating favicons?

High-resolution square PNG or SVG graphics with transparent backgrounds produce the crispest favicons across dark and light browser themes.
