3Why convert PNG to ICO?
Understanding the strengths and limitations of each format helps you decide when converting from PNG to ICO makes sense. PNG was created in 1996 as a patent-free alternative to GIF after the Unisys LZW patent controversy. It rapidly became the standard for lossless web graphics. The ICO format was introduced with Windows 1.0 in 1985. It remains essential for web favicons and Windows application icons despite being nearly 40 years old.
