How do I convert HEIC to ICO?

Upload your HEIC file above. It is converted to ICO automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting HEIC to ICO lose quality?

Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.

HEIC or ICO: which should I use?

Use HEIC for saving storage space on iPhones and iPads. Use ICO for website favicons and Windows app or shortcut icons. Keep in mind the main drawback of ICO: icons are square and at most 256 × 256 pixels.

HEIC is how iPhones and iPads save photos by default. It needs up to half the space of a JPG at similar quality, but many Windows PCs, Android apps and websites still can’t open it.

What sizes does the ICO file include?

The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.

Why convert HEIC to ICO?

ICO is supported far more widely than HEIC, so the file is easier to open, share and upload.
One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.

What to expect when converting HEIC to ICO

Icons are square, so a non-square image is centred on a transparent square. Sizes larger than your image aren’t created, so start from at least 256 × 256 pixels.
High-dynamic-range and wide-colour detail is converted to standard 8-bit colour.
