What is WebP?
WebP is a modern image format developed by Google that provides both lossy and lossless compression. It typically produces files 25–35% smaller than equivalent PNG or JPEG images while maintaining comparable visual quality. WebP supports transparency (alpha channel), animation, and rich color profiles.
WebP has become the standard format for web-optimized images. Tools like Squoosh, Figma, and many CMS platforms export in WebP by default. However, when you need to create a favicon from a WebP logo or icon, you need to convert it to the ICO format that all browsers and operating systems recognize.
What is ICO?
ICO is the Windows icon format and the universal standard for website favicons. A single ICO file can contain multiple images at different resolutions (16×16, 32×32, 48×48, 256×256), allowing browsers and operating systems to display the most appropriate size for each context.
Every website needs a favicon.ico file. It appears in browser tabs, bookmarks, browser history, address bar suggestions, and desktop shortcuts. A missing or broken favicon signals an unprofessional website and makes your site harder to find in a crowded tab bar.
Standard Favicon Sizes in ICO
| Size | Where It’s Used | Notes |
|---|---|---|
| 16×16 | Browser tabs, address bar | The classic favicon size. Required for every website. Displayed in all browsers. |
| 32×32 | Retina browser tabs, taskbar shortcuts | Used on high-DPI displays and Windows taskbar pins. Provides crisper icons on modern screens. |
| 48×48 | Windows desktop shortcuts, site icons | Used when users create desktop shortcuts to your website. Also appears in Windows Explorer. |
For best results, start with a square WebP image at least 256×256 pixels. The converter automatically generates all sizes needed for the ICO container.
When to Use ICO Format
Website favicons
The primary use case for ICO files. Place favicon.ico in your site root and every browser will find it automatically. While modern browsers also support PNG and SVG favicons via <link> tags, ICO remains the universal fallback — it works in every browser including legacy versions of Internet Explorer.
Windows application icons
Windows applications use ICO files for their icons in the taskbar, Start menu, and desktop shortcuts. If you're building a Windows app or Electron-based application, you need an ICO file. Converting your WebP design asset to ICO is a required step in the build process.
Multi-resolution in one file
Unlike PNG or WebP, ICO can store multiple sizes in a single file. The operating system or browser automatically picks the right size for each context — 16×16 for tabs, 32×32 for taskbar, 48×48 for desktop. No need to manage separate files for each resolution.
Maximum compatibility
Some browsers and platforms support WebP or PNG favicons, but only ICO is universally supported. If you need your favicon to work on Internet Explorer, older Android browsers, or embedded WebView components, ICO is the safest choice. It's the only format guaranteed to work everywhere.
