Why Convert TIFF to ICO?

ICO is purpose-built for icons and favicons:

  • Multi-size in one file: 16–256 px variants bundled for crisp rendering.
  • Favicon standard: Works across major browsers.
  • Windows native: Ideal for desktop/app/shortcut icons.
  • Transparency: Alpha support for smooth edges.

How to Convert TIFF to ICO Online

  1. Click Upload TIFF and select your image.
  2. Wait for processing and optimization.
  3. Click Download ICO to save your icon.

We generate common icon sizes automatically.

Supported Limits & Formats

  • Accepted input: TIFF (image/tiff)
  • Maximum file size: up to 16 MB per file
  • Output: ICO (.ico, MIME image/x-icon)
  • Pages: Multi-page TIFFs: only the first page is converted.

Best Practices for Sharp Icons

  • Start with a square image and add padding to avoid clipping.
  • Use clear shapes and high contrast for 16–32 px sizes.
  • If you need transparent edges, ensure the TIFF contains an alpha channel or convert a PNG with transparency instead.

Troubleshooting

  • Favicon not updating: Clear browser cache and ensure you link /favicon.ico with <link rel="icon" href="/favicon.ico">.
  • Jagged small sizes: Upload a larger, clean source; the tool will downscale to 16–32 px.
  • Upload fails: Confirm image/tiff and ≤ 16 MB.

  • Yes, the converter is completely free with no hidden charges or subscriptions.
  • ICO is natively supported on Windows and recognized by major browsers. macOS/Linux tools can view/edit ICO as well.
