Format referenceWhy convert ICO to WEBP?
- Compatibility is the main reason to convert when another person or service cannot open the source.
- 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.
- WebP is more appropriate for the target application, device, or delivery channel than ICO.
Will quality change?
The WebP encoder is lossy. Fine text, sharp edges, and subtle gradients are the first places to check after conversion. Check a sample before processing a large batch.
