Why convert PNG to ICO?
PNG is a lossless format that keeps every pixel intact and supports a full alpha (transparency) channel. Files are larger than JPG but quality never degrades. ICO is the Windows icon container, used for application icons and website favicons. It can hold one or more small images, typically 16x16 up to 256x256 pixels.
- Generate a Windows favicon or app icon — ICO is the format browsers and Windows expect for icons.
- Improve compatibility — ICO is widely supported and easy to use across the apps and platforms you rely on.
