Frequently Asked Questions

What is a favicon .ico file?

A favicon (favorite icon) is a small icon file associated with your website, displayed in browser tabs, bookmarks, history, and shortcuts. The .ico format is a container that can hold multiple icon sizes in a single file — typically 16×16, 32×32, and 48×48 pixels — ensuring your icon looks sharp across all platforms and resolutions.

Why do I need multiple sizes in one .ico file?

Different operating systems and browsers display favicons at different sizes. Windows taskbar might use 16×16 or 32×32, macOS Dock uses larger sizes, and browser tabs vary. A multi-size .ico file ensures every platform picks the optimal resolution, preventing blurry or pixelated icons. Including sizes like 16, 32, 48, 64, 128, and 256 px covers virtually all use cases.

What are the recommended favicon sizes for 2025?

The essential sizes for a comprehensive favicon.ico are: 16×16 (browser tabs), 32×32 (Windows taskbar, shortcuts), 48×48 (Windows desktop, file manager), 64×64 (modern browsers), 128×128 (high-DPI displays), and 256×256 (macOS, progressive web apps). For Apple Touch Icons, you'll also need a separate 180×180 PNG. Our generator includes all these sizes.

How do I add the generated favicon to my website?

Place the favicon.ico file in your website's root directory (public_html or www). Then add this line inside your HTML <head>:
<link rel="icon" type="image/x-icon" href="/favicon.ico">
Most browsers will also automatically look for /favicon.ico in the root folder. For best results, also include PNG fallbacks and Apple Touch Icons.

What image formats can I upload as source?

Our tool supports PNG, JPEG, SVG, GIF, WebP, and BMP files up to 10 MB. PNG with transparency is recommended for the best results. SVG files will be rasterized during conversion. Note that animated GIFs will only use the first frame, and extremely large images will be scaled down automatically.

Does the tool preserve transparent backgrounds?

Yes! In Square Crop mode, transparency is fully preserved — ideal for logos and icons with transparent backgrounds. In Fit mode, you can choose a background color (default white) to fill any empty space around your image, which is useful for non-square source images that you want to keep fully visible.

Why is my SVG not rendering correctly?

SVG files with embedded external resources, complex filters, or foreignObject elements may not rasterize properly in all browsers. For best results, ensure your SVG has explicit width and height attributes and uses standard vector shapes. If issues persist, try converting your SVG to a high-resolution PNG first (e.g., 512×512) and uploading that instead.

How long does it take for a new favicon to appear?

Browser caching can delay favicon updates. Changes may appear within minutes on your local machine, but visitors may see the old icon for days or weeks due to aggressive caching. To force a refresh, you can add a version query string: href="/favicon.ico?v=2". Clearing your browser's cache or testing in an incognito window also helps verify the new icon immediately.

Can I use this tool for commercial projects?

Absolutely. This tool is free for personal and commercial use. All processing happens locally in your browser — your images are never uploaded to any server. You retain full ownership of your designs, and the generated .ico files can be used on client websites, apps, and commercial products without attribution.

What's the difference between .ico and .png for favicons?

A .ico file can contain multiple icon sizes bundled together, while a .png is a single-size image. The .ico format offers broader legacy support (Internet Explorer, older Windows versions), but modern browsers also support PNG favicons via <link rel="icon" type="image/png">. For maximum compatibility, we recommend using both: a multi-size .ico plus separate PNG icons for Apple Touch and Android.

Privacy note: All image processing happens entirely in your browser. Your images are never uploaded to any server. This tool works offline too — once the page loads, no internet connection is needed.
