Does converting ICO to WebP lose quality?

WebP is lossy by default, so some fine detail is discarded to make the file smaller. Raise the quality or switch on lossless in Settings for a closer copy.

Using an ICO icon on a web page as WebP

When a site shows icons inside its pages, as feature bullets, app tiles or a list of links, the browser needs an image format rather than an .ico. WebP fills that role with transparency intact and tiny files. The converter takes the largest picture inside the icon file.

Icons are graphics with hard edges and flat color, so Lossless mode is usually the better choice: it keeps every pixel, and at icon sizes the file is still small. Lossy WebP at high quality is fine for photographic app icons. View the result in the Website preview to judge it against a page background.

If the icon must fill a specific display size, such as 64 pixels for a 32-pixel slot on a high-density screen, resize it with WebP as the output, but not beyond the largest size stored in the .ico. To build an icon set for your own site rather than reuse one, generate a favicon pack.
