Why convert AI to ICO?
- The new format may support a feature the source container does not.
- The result can be reviewed without changing the file that other people still use.
- ICO is more appropriate for the target application, device, or delivery channel than AI.
- Compatibility is the main reason to convert when another person or service cannot open the source.
Will quality change?
The ICO output stores decoded pixels without another lossy compression step. It cannot recreate detail the source already lost, and the file may be larger. Keep the source if you may need to adjust the conversion later.

Platform compatibility
The output is a ICO file. Use an application or device that accepts that format, and test the result on the destination platform if compatibility is critical.
When not to convert
- Do not use a converted file as the legal or signed original when signatures or metadata must be preserved.
- Do not overwrite the source; keep both versions until the output has been approved.
- Avoid repeated lossy conversions when quality matters; start from the highest-quality source available.
