About PNG to ICO Converter

Turn any PNG into a Windows ICO icon for favicons or desktop use. Images larger than 256px are downscaled proportionally; transparency is preserved.

All conversion happens locally in your browser using canvas and WebAssembly decoders — your files are never uploaded to any server. Drop an image or paste it to get the converted file instantly, in batches if needed.
