HEIC to ICO

What is HEIC?

HEIC (High Efficiency Image Container) is a modern image format introduced by the Moving Picture Experts Group as part of the HEIF standard. HEIC uses advanced compression to store images at roughly half the file size of an equivalent JPG while maintaining the same visual quality. HEIC also supports 16-bit colour, transparency, and multiple images in a single container (for example, bursts and live photos). Apple adopted HEIC as the default photo format on iOS 11 and macOS High Sierra, so most photos taken on an iPhone are HEIC files.

What is ICO?

ICO is the historical icon container format introduced by Microsoft in 1985 for Windows 1.0. An .ico file is a small container that can hold one or more bitmaps or PNG-compressed images at different sizes (typically 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256) and color depths. Browsers, the Windows shell, bookmark managers, and desktop shortcuts all look for an .ico file (commonly favicon.ico) at the root of a website to display the site's icon.

HEIC vs ICO comparison

HEIC and ICO serve very different purposes: HEIC is a modern photo format optimised for compression, while ICO is a legacy icon container designed for favicons. The table below summarises the key differences.

Format type	Modern photo container	Legacy icon container
Compression	HEVC (very efficient)	BMP or PNG embedded
Typical use	iPhone photos	Favicons, app icons
Multiple sizes	Multiple images	Yes

When to use HEIC to ICO conversion

Converting a HEIC photo to an .ico file is useful when you want to turn an iPhone photo into a favicon. Common scenarios include:

• Personal website favicon. Use a favourite iPhone photo as your site's icon.
• Desktop shortcut from a photo. Create an .ico from a HEIC portrait for a desktop shortcut.
• Brand icon from a photo. Crop a HEIC photo to a logo and export it as a favicon.
• Bookmark icon. Provide a real favicon.ico so bookmark managers show your icon.
• Windows app icon. Use the HEIC-derived .ico as a Windows application icon.
