About the PNG to ICO
The Img Stop PNG to ICO Converter turns PNG images into .ico icon files and keeps their transparency, so a logo with a see-through background becomes a clean icon without a white box. Save each icon at one size (16, 32, 48, 64, 128 or 256 px) or as one multi-size .ico holding 16, 32, 48 and 256 px.
PNG is the most common starting point for favicons and Windows icons. If your PNG is not square, it is centred on a transparent square instead of being stretched. You can convert many PNG files at once, and everything happens in your browser – nothing is uploaded, with no sign-up and no watermark.
