ICO to PNG
Drop in a Windows ICO (or favicon.ico) file and download a lossless PNG of the largest embedded image. ICO files can contain multiple sizes — this tool picks the highest-resolution entry. If the entry is stored as PNG (common for 256×256 icons) it's extracted byte-for-byte; otherwise the BMP-formatted entry is decoded and re-encoded as PNG, preserving transparency where present. Conversion runs locally in your browser — files never leave your device.
