PNG stands for Portable Network Graphics. It was created in the mid-1990s as a free and open alternative to the older GIF format. PNG was officially released on October 1, 1996, and later adopted as a standard by the W3C (World Wide Web Consortium).
PNG is best known for supporting lossless compression which means the image quality stays exactly the same after saving. It also supports transparent backgrounds, making it useful for web design, logos, and UI elements.
However, PNG files are usually larger than JPEG or WEBP because they don’t remove any image data. This makes PNG ideal when image quality and sharpness are more important than file size.

ICO file is a type of computer file used to store icons. Icons are small pictures representing programs, files, folders, or computer functions. ICO files contain multiple icon images in different sizes and with different color details. This allows the icon to display clearly and sharply in different contexts and sizes on your screen.
The ICO format was created by Microsoft. It was first used in Windows 1.0 in 1985. ICO files support transparency. This means that parts of the icon can be seen, so the icon can look good on a different backgrounds. ICO files typically include image sizes ranging from 16×16 pixels to 256×256 pixels, and sometimes larger.
