How to Convert AVIF to ICO — Quick & Free
Fast, instant AVIF to ICO conversion. No signup required. Just drop your .avif file and get .ico in seconds.
Batch Settings
HDR data will be tone-mapped
Your AVIF file may contain HDR (High Dynamic Range) data. ICO only supports standard dynamic range (SDR). Highlights and shadows will be compressed to fit the 8-bit range — subtle detail in very bright or dark areas may be lost.
Animation frames will be lost
AVIF supports animation, but ICO does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
Some metadata may not survive
Your AVIF file may contain EXIF, XMP, ICC metadata. ICO has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Wide color gamut → sRGB
Your AVIF file uses a wide color gamut (sRGB, Display P3, BT.2020 wide gamut). ICO uses standard sRGB. Highly saturated colors outside the sRGB range will be clipped or compressed — this is most noticeable in vivid reds, greens, and blues.

在中国大陆及周边地区，ICO格式在桌面应用程序和系统图标方面仍有广泛应用，尤其是一些老旧系统或特定行业软件，对ICO格式的兼容性要求较高。同时，考虑到移动端分享，将AVIF转为ICO后，若需在微信等平台分享，通常还需要进一步转为PNG或JPG，以确保最佳兼容性。
