Why Convert HEIC to ICO?

ICO is the standard favicon format recognized by all browsers. While modern browsers also accept PNG favicons, ICO remains the most compatible option and can embed multiple resolutions in a single file.

How to Convert HEIC to ICO

1

Upload your HEIC photo. A square image or logo works best for favicons.

2

KoalaPic generates a multi-resolution ICO file with 4 standard sizes embedded.

3

Download your ICO file and add it to your website’s root directory as favicon.ico.

💡

Quality Note

The image is resized to fit standard favicon dimensions. For best results, start with a square image. Non-square images will be scaled to fit, which may crop or distort the composition at very small sizes.

Frequently Asked Questions

Use ICO for maximum compatibility. Modern browsers support PNG favicons, but ICO is recognized everywhere, including older browsers and Windows shortcuts.
Technically yes, but photos don’t work well at 16×16 pixels. Simple logos, letters, or icons with high contrast work best for favicons.
