ICO Viewer - Open Windows Icon Files on Android & Online

ICO is the icon format of Microsoft Windows: application icons, shortcut icons and website favicons all use it, and one file can carry the same image in several sizes and color depths. Support for the format is weak outside Windows, and most Android image viewers do not recognize it at all.

GroupDocs.Viewer Cloud renders an ICO file to PNG, JPG, PDF or HTML over one REST call, so a design review app, an asset catalog or a download manager on Android can display the icon as an ordinary image. The Java SDK, installed via Maven or Gradle, comes with samples, and zoom matters here in particular, because icons are small and their pixel detail is what a reviewer needs to inspect. The same calls handle the other 180+ supported formats, so a tool that previews ICO can preview PNG and JPEG sources with no extra code.

Checking a single favicon takes only the free online GroupDocs.Viewer app. For integration work, the interactive API Explorer exposes every endpoint, and a free trial provides the same calls from Java.
