How do I convert a HEIC file to ICO using LetsConvert?

Upload your HEIC file, select ICO as the target format, and click Convert. The tool decodes the HEIC image, re-encodes it into ICO with embedded PNG/BMP frames, and downloads the icon file. For best results, make sure the original is a square image with a transparent background.

Why should I convert HEIC to ICO?

HEIC is Apple's space-saving photo format based on HEVC compression, but it is not natively supported by Windows icon viewers or many web browsers. ICO is the standard container for Windows icons, favicons, and application shortcuts. Converting HEIC to ICO enables you to use your images as icons with transparency and multiple resolution variants.

What happens to transparency, resolution, and color depth when converting HEIC to ICO?

The HEIC image is decoded and re-encoded into a 32-bit BGRA ICO file. This preserves the alpha channel for transparency. HEIC's 16-bit depth and HDR data are converted to 8-bit per channel, as ICO supports only 8-bit per channel. We also generate standard icon sizes—16×16, 32×32, 48×48, and 256×256—from the original to keep edges sharp.
