Converting WebP to ICO produces a Windows icon file with proper alpha channel support. WebP sources with transparency convert cleanly into multi-resolution icons suitable for favicons, shortcuts, and application icons.

The converter generates standard icon sizes (16, 32, 48, 256) by downscaling the WebP. Quality at small sizes depends on the source resolution; start with at least 256×256 for good results at every size.
ICO is handled by every browser (for favicons), every Windows version, and every icon-aware tool. It's the native Windows icon format.
WebP is Google's 2010 image format based on the VP8 video codec. It offers lossy and lossless modes, full alpha transparency, and animation in a single container. At matched quality it's typically 25–35% smaller than JPG or PNG. Every major browser has supported it since 2020.
ICO is the Windows icon format. A single .ico file can hold multiple resolutions (16×16, 32×32, 48×48, 256×256) and color depths simultaneously, letting the OS pick the best for context. Every browser serves favicons as ICO, and Windows desktop icons use it natively.
Yes. ICO supports alpha channels, and WebP's transparency transfers cleanly. Icons will have proper soft edges against any background.
Standard Windows sizes: 16×16, 32×32, 48×48, and 256×256. Windows and browsers pick the closest match for whatever they need to display.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
