Common Uses for ICO Files

From website favicons to Windows app icons - ICO is the format you need.

Website Favicon

The tiny icon in your browser tab. Browsers require ICO format for the widest compatibility across all browsers and OS versions. Use a 32x32 or 64x64 PNG for the best favicon results.

Windows App Icons

Every Windows application needs an ICO file for its taskbar, Start menu, and desktop shortcut icons. A multi-size ICO ensures crisp display on every screen DPI.

Custom Folder Icons

Personalize your Windows folders and file shortcuts with custom ICO icons made from your own logos and graphics.

Electron / Desktop Apps

Electron and other cross-platform desktop frameworks require ICO files for Windows builds. Our batch converter handles entire icon sets in one go.

Frequently Asked Questions

Everything you need to know about PNG to ICO conversion.

An ICO file is a special image container format used for computer icons in Windows and for website favicons. Unlike a regular PNG, an ICO file can store multiple image sizes (16x16 up to 256x256 pixels) in a single file, letting the OS or browser pick the best size automatically. You need ICO for website favicons, Windows app icons, and custom desktop shortcuts.
Convert your logo PNG to ICO using this tool, name the file favicon.ico, and upload it to your website's root directory. Then add this line inside the <head> tag of your HTML: <link rel="icon" type="image/x-icon" href="/favicon.ico">. Most browsers will also find favicon.ico automatically without the link tag if it is in the root.
Each converted ICO file contains 9 sizes: 16x16 (browser tab), 20x20, 24x24 (Windows toolbar), 32x32 (standard desktop), 40x40, 48x48 (file explorer), 64x64, 128x128, and 256x256 (high-DPI, Vista+). All sizes are embedded in a single .ico file.
Yes, completely. Your uploaded PNG files and converted ICO files are automatically deleted from our servers right after processing. We do not store, share, sell, or analyze your images in any way. The tool runs entirely for your benefit, not ours.
Yes. Drag and drop up to 50 PNG files at once. Each is converted independently. Once you have converted 5 or more files in a session, a ZIP download button appears automatically so you can download all your ICO files as a single archive.
For the sharpest results, use a square PNG image at 256x256 pixels or larger. The converter handles any size or aspect ratio - non-square images are centered on a transparent canvas automatically. Files must be under 2 MB each.

PNG vs ICO: Understanding the Difference

Both PNG and ICO support transparency and lossless compression, but they serve different purposes. PNG is a universal web image format - perfect for photographs, UI graphics, and logos. ICO is a container format specifically designed for operating system icons, holding multiple image sizes in a single file.

PNG (Portable Network Graphics)

  • Best for web images and graphics
  • Full alpha-channel transparency
  • Lossless compression
  • Single image per file
  • Supported in all browsers

ICO (Windows Icon Format)

  • Required for .exe icons and favicons
  • Stores multiple sizes in one file
  • 16x16 to 256x256 pixels
  • Full transparency support
  • Native to Windows OS
