How to use

  1. Add a square logo or icon (crop first if the subject is off-center).
  2. Select the sizes you need (16×16 through 256×256).
  3. Generate and download favicon.ico plus optional PNG files.

Key benefits

  • Real ICO output

    Downloads a multi-size ICO with PNG entries—not a renamed single PNG.

  • Multiple sizes

    Create the common browser and shortcut sizes in one pass.

  • Private

    Your logo never leaves the browser for favicon generation.

Prepare a sharp source

Start from a high-resolution square master. Soft or tiny sources look blurry at 16×16. Use Crop Image if you need to center the mark first.

For a single ICO from an existing icon file, see also the ICO converter.

Where to use the files

Place favicon.ico at the site root or link PNG sizes in your HTML head. Keep filenames stable so browsers cache updates correctly after a redesign.

FAQ

Common questions

Is favicon.ico a renamed PNG?

No. This tool builds a multi-size ICO container with PNG image entries, which modern browsers accept.

Which sizes should I pick?

16×16 and 32×32 cover classic tabs. Add 48×48 and 180×180-style PNGs when you also need shortcuts or touch icons. This generator focuses on common ICO/PNG packs up to 256×256.

Are my images uploaded?

No. Favicon generation runs in your browser.

Should the source be square?

Yes for best results. Non-square images are fitted into a square canvas and may letterbox or crop depending on the source.
