Frequently Asked Questions

A favicon is the small icon displayed in browser tabs, bookmarks, and search results. It helps users identify your site quickly and improves brand recognition. Search engines also use favicons in mobile results, making them essential for modern web presence.

The .ico format can contain multiple image sizes in a single file. Browsers automatically pick the best size for each context (tab, bookmark, shortcut). While modern HTML allows PNG favicons, using .ico ensures maximum compatibility with older browsers and systems like Windows shortcuts.

The minimum recommended set is 16×16, 32×32, and 48×48 pixels. For full coverage across devices and platforms, include 64×64, 96×96, 128×128, and 256×256. Our tool lets you pick any combination and generates a multi‑size .ico instantly.

Upload the .ico file to your website's root directory and add this line inside the <head> of your HTML: <link rel="icon" type="image/x-icon" href="/favicon.ico">. Modern sites can also use a site.webmanifest for advanced icon settings.

Yes! Our converter supports PNG, SVG, WebP, and other common formats. Transparency is preserved in the generated .ico because we use 32‑bit BMP with alpha channel internally. The result will look crisp on both light and dark browser themes.

Absolutely. All processing happens inside your browser — your image never leaves your device. No uploads to any server, no watermarks, no hidden costs. Convert as many icons as you like.

There’s no hard limit, but for best performance we recommend images under 5 MB. Large files are automatically resized to your chosen dimensions, so even high‑resolution photos will produce a tiny favicon file.
