ICO is a Windows-specific icon container, while WebP was built by Google specifically for fast-loading websites, supporting both lossy and lossless compression along with a full alpha channel. Converting ICO to WebP is useful when a logo or icon design needs to be published on a website, since browsers widely support WebP but have no native support for ICO's multi-resolution structure.
WebP's lossless mode preserves the icon's exact appearance and transparency, while lossy mode shrinks the file further if some compression is acceptable for a small icon graphic.

Why publish an icon as WebP instead of ICO?
Browsers have no native support for ICO's multi-resolution structure, while WebP is widely supported and produces efficient file sizes for web use.
Will my icon's transparency carry over to WebP?
Yes, WebP supports a full alpha channel, so any transparency in the original ICO file transfers cleanly to the converted file.
Can I convert an entire folder of ICO files to WebP at once?
Yes, Batch Mode handles entire folders, including nested sub-folders, and scales conversion speed across multiple CPU cores.
