Convert HEIC to ICO
What is HEIC?
HEIC
HEIC (High Efficiency Image Container) uses HEVC (H.265) compression for approximately 50% better compression than JPG while maintaining similar quality. Part of HEIF standard (ISO/IEC 23008-12). Supports transparency, animation, multiple images, and metadata. Default format for iOS photos since iPhone 7. Maximum resolution 65,536×65,536 pixels. Requires royalty-bearing codec licenses.
- HEIC uses lossless compression for perfect quality image storage
- Alpha channel transparency requires background color for ICO conversion
- Modern format—requires up-to-date software for compatibility
What is ICO?
ICO
ICO stores multiple bitmap images at various sizes and color depths (1-bit to 32-bit with alpha) in a single file. Designed for Windows application and website favicons. Contains multiple representations (16×16, 32×32, 48×48, 256×256) for different display contexts. Can store both BMP and PNG formats internally. Maximum 256×256 pixels per image. Supports transparency.
- ICO uses lossless compression for perfect quality image storage
