Why convert HEIC to ICO?

Converting HEIC to ICO lets you take advantage of ICO's stores multiple resolutions (16x16 through 256x256) in one file. HEIC files (High Efficiency Image Container) can be converted to ICO (Icon File Format) for better compatibility, smaller file sizes, or access to features that HEIC does not support.

HEIC vs ICO: technical comparison

HEIC (High Efficiency Image Container, introduced in 2015) uses HEVC (H.265) intra-frame compression. ICO (Icon File Format, introduced in 1985) uses None (BMP payload) or PNG payload compression. HEIC supports animation, but ICO does not. Only the first frame will be preserved during conversion. HEIC browser support: Limited (Safari only on macOS/iOS). ICO browser support: Universal.

What happens to quality?

The quality impact depends on the specific settings used during conversion. ICO preserves full quality with lossless compression.

File size impact

Typical HEIC file size: A 12MP iPhone photo: ~1.5-2.5 MB. Typical ICO file size: A multi-size favicon (16+32+48+256): ~15-100 KB.

Common use cases

  • Converting iPhone photos for sharing with Windows and Android users
  • Creating website favicons from HEIC source images
  • Converting HEIC files to ICO for compatibility with specific applications or workflows
Pro tip

To avoid HEIC conversion hassles entirely, go to iPhone Settings, then Camera, then Formats, and select "Most Compatible" to shoot in JPG directly. You can also enable "Automatic" transfer mode which converts to JPG only when sharing.
