ICO to PNG converter

ICO is a graphics file format used for computer icons. It was created by Microsoft for use with Windows, and most image editors support the creation and saving of this image type. ICO files contain small images and are typically saved in either 16x16 pixel or 32x32 pixel sizes, but larger sizes are also supported.

ICO files use a specific header which contains metadata, followed by an array of bits that represent the pixels. It supports several color depths (typically 1, 4 and 8 bits per pixel) and can include optional transparency and alternative image formats. ICO files can sometimes contain multiple sizes or variations of the same icon, allowing it to be scaled to different sizes while maintaining a consistent appearance.

PNG stands for Portable Network Graphics and is a lossless image file format used for storing graphics on the web. PNG files are supported by most modern web browsers and can be scaled up or down without loss of quality. Compared to traditional bitmap formats like JPEG and GIF, PNG produces smaller files with better compression, resulting in higher image quality.

PNGs support transparency, alpha blending, anti-aliasing, and multiple identifiers. They also include 8-bit and 24-bit color depths which can produce smaller file sizes than more traditional formats such as GIF. Additionally, the ICC color profile can be included with any PNG file for improved color accuracy.
