history
Project history and usage
png2ico is a portable command-line converter that combines one or more PNG images into a Windows ICO resource, commonly for use as a website favicon.
Project history
Matthias Benkmann developed png2ico as a small GPL-licensed utility for creating Windows ICO resources from PNG images. The official page carries a 2000–2010 copyright notice and distributes source and Windows packages dated 8 December 2002.
Adoption history
The program was released for Windows as a ready-to-run console application and for Unix-like systems as portable source. It subsequently appeared in packaging systems including Homebrew, MacPorts, Chocolatey, and Windows Package Manager.
How it is used
Users provide an output ICO filename followed by one or more PNG inputs, typically multiple resolutions of the same artwork, such as `png2ico favicon.ico logo16x16.png logo32x32.png`.
Why package nerds care
png2ico is characteristic of early cross-platform Unix freeware: one executable, one conversion job, no account or daemon, and a source tarball that remains packageable decades later. Its preservation in package managers keeps an old but still useful favicon workflow available.
Timeline
- 2000: The official copyright period begins.
- 2002-12-08: The currently published source and Windows packages were released.
- 2010: The copyright range shown on the official project page ends.
Related projects
- png2ico operates between the PNG image format and Microsoft's ICO resource format and was commonly used to create favicon.ico files for websites.
