What happens when you convert HEIF to ICO
- HEIF is another name for HEIC; files ending in .heif work here.
- iPhone photos use wide-gamut Display P3 color; it's converted to standard sRGB so colors look right everywhere.
- Works in Safari, Chrome and Edge. Firefox can't open HEIC yet.
- ICO is lossless, so nothing more is lost in the conversion. Detail already removed by HEIF compression doesn't come back, and the file is usually larger.
- Transparency is kept.
- Choose the icon sizes (16 to 256 px); they're all packed into one .ico file, ready to use as a favicon.
