How to Convert HEIC to ICO

ICO is the Windows-specific format used for application icons, file type icons, and website favicons, bundling multiple sizes of the same image (commonly 16×16 up to 256×256 pixels) into a single file. HEIC photos are rarely the ideal source for icons, since icons are typically displayed very small and benefit from simple, high-contrast source images rather than the fine detail and dynamic range a typical iPhone photo captures.

That said, converting an iPhone photo to ICO is sometimes needed when you want to turn a personal photo into a custom folder icon or shortcut icon on Windows, and the conversion process simply needs to decode the HEIC content and package it into the ICO container Windows expects.

1. Install Turbo Batch Image Converter Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single HEIC file.
3. Drag your HEIC file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to HEIC and the "To" format to ICO.
5. Click Convert. ICO files are written to the output folder, fully offline.
